Heaved upwards from your deep and watery grave,

From the quiet murk onto a chaotic, brine-encrusted ship deck,

You’re ever so carefully washed free from the mud,

From all the rinsings of continents that settled out of the sea with you

Like snow, softly entombing your remains.

Now through my looking glass, you lie scattered

Like discarded Christmas ornaments,

Lying in broken glory, shards of a former world;

Tiny fossils, utterly bewitching.

Some people say there must be a knowing architect behind all this design;

Looking at your tiny turrets, buttresses, embellishments,

I understand the sentiment.

How is it, and why is it, that you craft such castles

Smaller than a grain of sand?

I know it is your work, not that of some artful watchmaker;

I’ve watched your live descendants raise their miniscule arches,

Lay down their mortar and stone, precisely and perfectly.

Still, it’s hard to believe my eyes. I am desperate to ask you,

Clever protist with no brain, to tell me all your secrets.

I wonder if some life-form, eons hence,

Will ever find my ancient bones,

Marvel at their beauty,

And imagine the life of the mysterious being that grew them.

Far away, a beloved dot

Arcs through cold and shrouded spaces,

Not lonely, as we had once thought,

But circled by more rocky faces:

Charon, Nix, and Hydra found,

Classified as “dwarf” or pseudo,

And though such bodies now abound,

None sparks wonder quite like Pluto.

On the hunt for Planet X,

Tombaugh found a ball of light,

Among a crowd of tiny specks;

Imaginations soon took flight.

Elusive is this outerworld;

Nine years ago we took a dare –

To deepest space, a scouter hurled

… and soon it will be there!

‘Faux pause’

Geopoetry - Fri, 06/12/2015 - 10:30
 Maintenance workers on an ocean buoy, NOAA.

The global ocean buoy network has been expanding in recent years. Accounting for small, consistent offsets between temperatures measured by buoys and by ships reveals a greater global warming trend than previously calculated for the past 15 years. Image: Maintenance workers on an ocean buoy, NOAA.

 

New data support the conclusion

The “hiatus” was mostly illusion.

They say that the keys

Are the poles and the seas …

The next job: reduce the confusion.

Smooth Sailing Back to Tasmania

Melting Glaciers-Tracking Their Path - Fri, 05/01/2015 - 10:12
Antarctica, NBP1503 science team

The NBP1503 science team.

After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

Once the equipment is stored away and the samples are loaded off, we will all head back to our offices and labs to further process and analyze our data and eventually put all the results together.

Taking a 4,000-Meter-Deep Profile of Antarctic Waters

Melting Glaciers-Tracking Their Path - Mon, 04/27/2015 - 10:47
NB Palmer, West Antarctica, CTD system

The CTD system is lowered over the side from the NB Palmer. It measures temperature, salinity, and oxygen with depth.

In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

To measure water properties, we are using an instrument that can be lowered through the water column that measures conductivity, from which we calculate the salinity of the water, temperature, pressure (i.e. water depth), oxygen, and fluorescence, which is an indicator for phytoplankton or algae in the water. This system is called a CTD for short.

This system can also take water samples from different depths that can be used for further analysis or for calibration and verification of the sensors. When we lower this system in deep water, e.g. 4000 meters, (about 2.5 miles), the measurements take over three hours.

We have measured the water properties at 42 different locations during our expedition and will analyze the results carefully when we are back.

Mapping the Seafloor

Melting Glaciers-Tracking Their Path - Mon, 04/20/2015 - 11:53
In addition to depth, we can identify many features in the high-resolution multibeam data that we produce. Most of the seafloor near the shelf break (where the water is between 300 and 500 meters deep) is covered with these irregular furrows that are created when large icebergs are grounded here.

In addition to depth, we can identify many features in the high-resolution multibeam data that we produce. Most of the seafloor near the shelf break (where the water is between 300 and 500 meters deep) is covered with these irregular furrows that are created when large icebergs are grounded here.

One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and ice streams.

The continental shelf in our study areas along the East Antarctic margin has been mapped in the past, but the existing data are very sparse and have many gaps. However, it is important to know the actual water depth of the continental shelf if we want to understand if water from the Southern Ocean with temperatures above the melting point could reach any glaciers and ice streams in this part of Antarctica.

We use a multibeam echosounder system installed on the Nathaniel Palmer to map the depth of a wide swath of the seafloor along our ship track. Access to the continental shelf is often limited by dense ice cover, but using the multibeam, we have managed to determine detailed depths in several areas. We will later analyze the depth data together with measurements of water column properties that will tell us exactly how deep the “warmer” Southern Ocean water is.

An Earth Epic

Geopoetry - Fri, 04/10/2015 - 10:30
 Ricardo Ramalho

Photo: Ricardo Ramalho

I hear that the Archean Earth

Spewed lava and was hot,

(While much later, “Snowball Earth,”

Apparently was not),

Some have said that life sprung out of

Spreading-ridge-type stew,

Photosynthesis seems likely

Based on carbon records, too.

Crust was forming, oceans warming,

Stromatolites came later,

(We have to wait a long, long time

for T-Rexes, Fish, and Gators)

The Prot’rozoic was really wild,

Stromatolites went crazy,

Our atmosphere gained oxygen,

The rest is a bit hazy.

Super-duper continents

and Banded-Iron formed;

Glacial stuff beneath cap carbs

Say Earth cooled and warmed.

Half a billion years ago

Is when it gets exciting …

Suddenly, life took a leap!

All living, breeding, fighting.

Brachs and Crinoids, Bryozoans,

Weirdo shells galore,

Nautiloids (like giant dunce caps)

Roamed the ocean floor.

Then disaster strikes them down,

(This happens four more times)

And we soon approach some names

That are difficult to rhyme.

Gondwana drifts to the South Pole,

and glaciers spread like malls,

The world was likely colder,

and sea level took a fall.

So ends the years of trilobites

(and the Ordovician)

But soon we get new forms of life,

And we can all go fishin’!

Finally the land joins in,

And starts to grow green stuff,

(are you still enjoying this,

or have you had enough?)

More death, more life, more death again,

While giant mountains grow,

(we think this lowered CO2,

but no one really knows).

The Carboniferous was lush,

(that’s where our coal is from!)

Amazing bugs and dinosaurs,

(though some say they were dumb).

Gymnosperms and vertebrates,

Then the grimmest death so far,

Then Triassic life recovered,

with reptiles big as cars.

We leave aragonitic seas behind

And move towards today,

Though continents were not in place,

(that great Tethys seaway).

About 100 million years ago

Deep sea carbonates abound,

So now the ocean’s buffered well,

(and planktics can be found!)

And THEN Earth has a real bad day,

An asteroid hits hard,

Fire-balls and darkened skies,

Life is burned and charred.

(Holy cow, this is quite long,

let’s finish it already!) …

Cenozoic history

was anything but steady.

It started hot, they also say

that CO2 was high;

Wimpy mammals take the lead,

(I hear that bats could fly).

Himalayas cause a ruckus,

Gateways open/close,

We start to get some glaciers,

And cold, deep water flows.

From the Greenhouse to the Icehouse

Now we’re really getting chilly,

Then humans come along (that’s us)

and everything gets silly!

So there you have it, Earth through time,

History deep and long,

I surely skipped a lot of stuff,

And may have got some wrong.

I hope if you’re still reading

that your brain is not too vexed,

Now it’s time to face the future,

…. I wonder what is next!

In the Ice

Melting Glaciers-Tracking Their Path - Fri, 04/10/2015 - 09:12
 The Nathaniel B. Palmer steaming through dense sea ice cover.

Some examples of the sea ice that we have encountered so far. Top left: bands of grease ice. Top right: small pancake ice merged together. Bottom left: larger pancake ice; bottom right: our ship, the Nathaniel B. Palmer, steaming through dense sea ice cover.

Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze. While the abundance of sea ice makes it more difficult to get to all of our research areas, the different shapes and forms of newly forming sea ice are a great visual experience. We also have a group of Australian scientists aboard the Palmer who are studying sea ice and sea ice formation using an unmanned aerial system or drone, so they are especially pleased by our icy experience.

Closing in on Antarctica

Melting Glaciers-Tracking Their Path - Mon, 04/06/2015 - 11:29
During our transit south to Antarctica we deployed seven ARGO floats (yellow device in picture) for the University of Washington. They drift with the currents in the oceans, measure profiles of salinity and temperature and send those via satellite to researchers on land. They are part of an international effort to better monitor the conditions of the oceans.

They drift with the currents in the oceans, measure profiles of salinity and temperature and send those via satellite to researchers on land. They are part of an international effort to better monitor the conditions of the oceans.

We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition. The CTD is used to determine the conductivity, temperature and depth of the ocean, while the multibeam maps large swaths of the seafloor from the ship.

The main goal of our project is to investigate the continental shelf in front of different glaciers along East Antarctica. We want to find out what the water depths and the water properties are in front of these glaciers and ice streams. Deep troughs and connections between the glaciers and the open ocean could allow “warmer” ocean waters to reach the ice front and result potentially in melting of the ice. We are especially interested to compare the situation in front of different glaciers along East Antarctica to better understand the differences between them. Many of these areas are poorly charted, if at all. So we are all excited to discover what is there!

Go Endeavor Go! Nighttime Adventures...

The ENAM Seismic Experiment - Sun, 04/05/2015 - 02:25
A unique low light vantage point of the Endeavor

A look at all the instrumentation on the bridge of the R/V Endeavor. 

The full moon as it shines over the ocean water! Creepy!

The OBS retrieval at night! One of the crew members installed a light at the end of the hook to aid in the equipment capturing process. 


This picture was take from the bridge of the Endeavor. It is the Quantum of the Seas cruise ship at ~0300 during an OBS retrieval. 
This picture is ~2 miles away from the Quantum of the Sea cruise ship and is as close as the Endeavor can legally pass another large ocean vessel under maritime law. The bright celestial object overhead is Jupiter.

This photo shows the Endeavor docked at port just before we embarked on this high seas adventure. The first evening we went to a chinese restaurant called 7 moons. By the time we arrived back at the shipyard the gate had been pulled shut and appeared to be locked and was topped with plenty of barbed wire. After some deep thought our highly intelligent group realized that it was pulled closed and all we had to do was roll it open haha. There is a geophysicists joke embedded in that experience. 

This is the WHOI crew carefully bringing the OBS back onto the ship. Hard hats and life preservers are required when on deck during retrieval operations. The OBS in this photo is hanging down beneath the orange apparatus.  

As the Endeavor aligns itself with the OBS in the ocean currents at night the WHOI crew get in position to capture the Ocean Bottom Seismometer. 


After a successful OBS capture the WHOI crew quickly disassembles the OBS and prepares it to be stacked with the other equipment that is strongly secured to the surface of the deck. 

This shows the spotlight at night. It is used to help orient the ship alongside the OBS in the pitch black darkness of the night at sea. We have also thankfully had the full moon over the last few days to assist us in finding the OBS once it pops up to the surface.

This lovely burry image is the spot light as it tracks the OBS. The spotlight is extremely useful once the OBS is within several ship lengths of distance. 


The OBS is starting to get closer now....

Full moon over a perfect OBS recovery.

Hammock in the middle of the night!

You can really get a good feel for spotting the OBS at night in this picture. It is obviously a ship length or two off the starboard bow.

Survival Suits to the Rescue!

The ENAM Seismic Experiment - Sat, 04/04/2015 - 16:20
Before the R/V Endeavor embarks on its research voyage the new crew/scientists get to enjoy the challenge of a mock sinking scenario where they have ~2mins to jump out of their shoes and wiggle into these fashionable lobster costumes.  

Dr. Maureen Long and one of the crew members race each other to safety!

Graduate Student intern Colton Lynner is almost unrecognizable once the survival suit is fully on. Only the last troublesome step up zipping up to go before full emersion can take place. 

Graduate Student intern Terry Cheiffetz struggles with the final zipper step as well. 

Dr. Maggie Benoit looks like she wants to really know how to put on the survival gear in case of emergency or... she can't believe she has to participate in these fun shenanigans.


The final product appears to be both fashionable and comfortable. We would interview the model in this photo but he declined to comment....hopefully next years model will have a mouth hole haha!



Living Quarters aboard the Endeavor

The ENAM Seismic Experiment - Sat, 04/04/2015 - 04:03
This is what the state rooms look like for the research scientists on the Endeavor. That lovely extra piece of wood wedged in on the top and bottom bunks help prevent us from falling out of bed in the middle of the night if the ship rolls more than expected.


Using the restroom at sea can be challenging at times...... especially when the seas unexpectedly turn on you while you are trying to take a shower. It is basically an unexplainable balancing act.


This lovely area is where we gather for three amazing meals a day and get an opportunity to socialize with some of the various crew members aboard the ship.

Maggie has about a million movies to choose from. They are an ancient technology called VHS used a long, long time ago....


The science deck is the room where all the magic happens. Everything from running the burn sequences on the OBS's to recalculating the surfacing locations due to variable ocean currents occurs here. The amount of technology on the Endeavor is impressive.

R/V Endeavor taking on water!!!

The ENAM Seismic Experiment - Sat, 04/04/2015 - 01:45
Short Video of the waves  crashing up onto the deck of the Endeavor


This 20 second video clip show just how dangerous life at sea can be! As the Endeavor rolls from one side to the next there is little to no warning as waves crash up and over onto the deck. Thankfully I was able to escape up the stairs to a somewhat dryer deck where the mist from the cresting waves and the wind were the only things able to assault my senses. The dangers out in the open on the ship at night are only multiplied by these variables.

Since the ship travels at ~10 kts between each OBS waypoint which can produce transit times as long as 12 hours and the weather isn't alway dreary the interns have a fair share of free time on the ship to explore around and lounge about.  

Checking to see if the internet wants to semi-work. I think Sampath knows he is in this picture.


Dr. Maureen Long creating a short cut to the relocated OBS equipment.


(Terry- I found two hammocks up on top of the ship perfect for some afternoon chill time haha. It also serves as a perfect vantage point when trying to find the OBS's when they reach the surface because the wave height and reflection of the sun off the water make it difficult to spot at times.)

After days of rough seas we all managed to gather up on the deck to take a group photo. The five of us are proud to be on the Research Vessel Endeavor and to finally have our sea legs. The Endeavor works around the clock out at sea and we worked in pairs on the following shift schedule, 0800-1600. 1600-2400, and 2400-0800. Each group had a PI in charge of their shift. The WHOI team was primarily in control of the extraction of the OBS in the rough seas due to the danger on deck and the sensitivity of the equipment.

This is a short video showing the Endeavor orienting itself alongside the OBS before the WHOI crew pulls it out of the water. It is clearly visible that both waves and weather play a major role when trying to retrieve the equipment from the ocean.

Graduate student interns are excited to locate the OBS on the surface after waiting over an hour as the instrument made its transit through the water column.  


It is only a matter of time before your feet get soaking wet out on the deck. The ocean only likes to do this though if you are wearing tennis shoes instead of waterproof boots!

Indian Sundarban

Geohazards in Bangladesh - Mon, 03/30/2015 - 13:34
Standing in front of the gates to the Queen Victoria Memorial in Kolkata

Standing in front of the gates to the Queen Victoria Memorial in Kolkata

We had a smooth trip to Kolkata with our two taxis amazingly staying together through the traffic. After checking in and freshing up, we went out for dinner and found a great Bengali Restaurant filled mostly with Bangladeshis around the corner. Our hotel turned out to be next to an area where Bangladeshis frequently stay, including Humayun previously. In the morning, he and I went for an early morning walk through the park and saw the Queen Victoria Memorial. Circling back past all the cricket players, we passed Fort William, the original British fort here, and joined Doug and Diane for breakfast. Our car arrived and before heading to the Sundarbans, we drove around to get shots of the Hooghly River. Before the 1600s, this was the main course of the Ganges, but since

A funeral procession arrived to scatter ashes in the Hooghly (Ganges) while we were filming

A funeral procession arrived to scatter ashes in the Hooghly (Ganges) while we were filming

then it shifted to it present course into Bangladesh. We got some shots from the new bridge before being chased off. Then we headed to the Strand to get close to the river. While we were filming, a funeral procession arrived to scatter ashes of the deceased into the river. Once the Holy Ganges, always the Holy Ganges. We couldn’t have planned it better.

Then, off to the Sundarbans. Where we were going was a lot farther than implied. This is because of a difference in naming. In Bangladesh, the Sundarbans is the National Mangrove Forest. The cultivated areas that previously were forest are not considered the Sundarbans. In India, they are. Thus we entered the Sundarbans after 2.5 hrs, but still had that long to go to meet our boat.

Humayun and Diane on the ferry – before it got crowded.

Admittedly, some of the cultivated areas in India still maintain mangroves outside of the embankments, which is not the case in Bangladesh. Continuing on, we reached literally the end of the road and carried our luggage (including a 50 lb. bag of rock samples) down to a ferry that took us to Gosaba. There, we first got a hand rickshaw to get the luggage across the town, then got two motorized rickshaw trucks to cross to the other side of the island. Finally, we were met by a boat that took us across the river to the eco-lodge where we would stay. After a late (4 pm) lunch we went on a sunset boat ride through some tidal channels. The saw and heard lots of bird and at times the channel became so narrow that we had to push branches away to fit through. The

Doug and Diane following me on their motorized rickshaw truck across Gosaba Island

trees here overhang the channels more than in Bangladesh. We would see further differences tomorrow. After finally showering off, we met other people staying at the eco-lodge, started by 4 cousins including Ajoy, who is leading our trip. The lodge is solar powered, so electricity is limited,but the water was refreshingly cool, not cold. We all heard a performance of Bengali Baul music, recognizing some songs from similar experiences across the border. After dinner, we all went for some local rice wine and then a boat ride to see bioluminescent plankton in a small channel. If you wave your hand in the water dots of light flash.

In the morning, we started at 6 am to have enough time before I had to head for the airport. We picked

up food and a cook and permits and a guide and finally were ready to enter the forest. In India, no one is allowed off the boat to step on the forest, nor to stay overnight in the forest, even on a boat. Thus many hotels and lodges have sprung up outside the forest for tourists. Many come simply to party and drink. We are very glad to be using an eco-lodge that is more respectful of the land and the local population.

At 8, we finally entered the national forest. Among the differences from the Bangladesh side we noted were the shorter height of the trees in the more saline water, the lack of sediment in the water, and the extent of bank erosion. Where the eastern Sundarbans is fresher with ample sediment carried by the tides due to its proximity to the Ganges-

Brahmaputra-Meghna River mouth, the western, Indian Sundarbans is more saline and lacks new sediment. Between subsidence and sea level, it is loosing ground. More land is being lost than gained. With the higher salinity, there is also less wildlife. However, there was a tiger sighting this morning. We sailed to the spot, but it was too late, we missed it. Still, we spent 4 hours sailing through tidal channels of different size, eating, and filming. Doug captured the beauty of the Sundarbans and I was interviewed with a great backdrop.

After completing our work, we briefly visited an observation post, we took a short cut through an interior channel in Gosaba Island, dropped off our guide, and crossed the channel to our car. Three hours later, I arrived here at the airport to start my journey home. It was an intense, yet calm 48 hours in West Bengal, the third leg of three very different pieces of this trip.

Map showing the planned track of our expedition with the modifications made due to the storm systems. Our main study areas are on the continental shelf in front of some major East Antarctic glaciers.

We are now aboard the R/V Palmer and on our way to East Antarctica. Due to two storms in our direct way we are heading west first to go around the storms and we’ll then head south on their backside. After passing the 200 mile zone off of Australia we turned some of the instruments on that collect data constantly while ship is under way. These instruments measure properties including surface water temperature, water depth, gravity, and weather data. In addition to their specific scientific missions research ships like the Palmer are also floating observatories that collect important data from remote areas of the world.
