As part of my PhD, I worked on the characterization of the geophysical signature of various processes in marine sediments:
In situ acoustic properties of calcareous sediments across an OpalA/OpalCT diagenetic front (Download PDF [2Mb])
Characterization of the in situ elastic properties of Gas Hydrate-bearing marine sediments (Download PDF [8Mb])
Reservoir Simulation to validate 4-D seismics (Download PDF [30Mb])
Numerical modeling of the thermal effect of fluid migrations in an active fault zone (Download PDF [11Mb])
But the best part of my work is sailing and collecting the data at sea...
I sailed as Logging Scientist onboard the R/V Joides RESOLUTION on the following cruises of the Ocean Drilling Program (ODP) and the Integrated Ocean Drilling Program (IODP) :
Leg 148 (1993): Return to Hole 504B, Costa Rica rift;
Leg 150 (1993): New Jersey Continental Slope and Rise;
Leg 158 (1994): TAG Hydrothermal Mound, mid-Atlantic ridge;
Leg 169 (1996): Sedimented Ridges II: Middle Valley and Escanaba trough;
Leg 185 (1999): Izu-Mariana Margin;
Leg 201 (2002): Deep Biosphere, Eastern Equatorial Pacific and Peru Margin;
Leg 204 (2002): Hydrate Ridge, offshore Oregon;
IODP Phase 1 mobilization (summer 2004): Gamagori to Astoria;
IODP Expedition 311 (fall 2005): Cascadia Margin Gas Hydrates;
IODP Phase 2 mobilization and sea trials (winter 2009): Singapore to Hawaii;
IODP Expedition 323 (summer 2009): Bering Sea Paleoceanography;
IODP Expedition 317 (fall 2009): Canterbury Basin Sea Level;
IODP Expedition 335 (spring 2011): Superfast Spreading Rate Crust 4;
IODP Expedition 340T (winter 2012): Atlantis Massif Core Complex;
Expedition 344S (summer 2012): Baffin Bay Scientific Coring Project;
IODP Expedition 345 (winter 2013): Hess Deep plutonic crust;
IODP expedition 350 (spring 2014): Izu-Bonin-Mariana Rear Arc.
In the latest incarnation of IODP, now the 'discovery program' where logging has been reduced, I sailed on one more expedition, with less responsibilities but the same pleasure at sea:
IODP expedition 362 (summer 2016): Sumatra Seismogenic Zone.
And my most recent IODP drilling expedition was onboard the Japanese vessel D/V Chikyu, to try to get samples and measurements deep into the seimogenic zone:
IODP expedition 358 (winter 2019): NanTroSEIZE Plate Boundary Deep Riser 4.
In recent years, I have mostly sailed on the R/V Marcus G. Langseth, providing support for acquisition of seismic surveys. A smaller vessel, with a much smaller crew and a more hands-on approach to operations. As I was monitoring the acquisition of terabytes of data, I started thinking of ways to illustrate the diversity of the data collected duting each cruise. Somehow I became the unofficial map maker and, one cruise at a time, increased the amount of data that could be displayed on a map:
MGL1405 (summer 2014): 3D Imaging of New Jersey continental margin;
MGL1408 (fall 2014): Mid-Atlantic US margin seismic experiment;
MGL1506 (april 2015): Atlantic US Extended Continental Shelf;
MGL1510 (june 2015): 3D Imaging of New Jersey continental margin;
MGL1512 (august 2015): Multibeam survey of US Extended Continental Shelf;
MGL1521 (fall 2015): Imaging the deep Santorini volcanic system;
MGL1610 (fall 2016): Imaging of the Pisagua/Iquique earthquake rupture;
MGL1701 (winter 2017): Crustal Examination from Valdivia to Illapel to Characterize Huge Earthquake (CEVICHE);
MGL1708 (fall 2017): Seismogenesis at Hikurangi Integrated Research Experiment (SHIRE), off New Zealand’s North Island;
MGL1801 (winter 2018): 3D survey off New Zealand’s North Island;
MGL1806 (fall 2018): Hawaii-Emperor Seamounts Phase 1;
MGL1902 (spring 2019): Hawaii-Emperor Seamounts Phase 2;
MGL1905 (summer 2019): 3D and 2D imaging of the Axial underwater volcano;
MGL2003 (summer 2020): Andreanof Experiment, Aleutian Arc.
I also worked as a shore-based scientist on shear sonic logging data from Leg 164 (1995): Gas Hydrate Sampling on the Blake Ridge and Carolina Rise;
spent most of the summer 2006 offshore India drilling for more gas hydrate during NGHP Expedition 1;
and some of the spring 2009 on the Q4000 logging for still more gas hydrate during the Gulf Of Mexico JIP Leg 2.

And if nothing else,
I run, even if my last marathon was a while ago,
Or digress about things.
