Estimated percent of subseafloor sedimentary respiration

Estimated percent of subseafloor sedimentary respiration supported by in situ water radiolysis at South Pacific gyre sites (in red box) (D’Hondt et al., 2009) and eastern equatorial Pacific sites (Blair et al., 2007).

Diagram of the Inverted Echo Sounder

Diagram of the Inverted Echo Sounder (IES): an ocean bottom-moored instrument that measures vertical acoustic travel time ( VATT ) round trip from the sea floor to the sea surface. GSO/URI currently produces Model 6.2 IES.

Tuning up the new FTIR system

Tuning up the new FTIR system: a Thermo Nicolet iS50 FTIR bench spectrometer coupled with a Continuum IR microscope, for analysis of C-O-H compounds in natural and synthetic materials. The microscope is equipped with 250 µm and 50 µm MCT-A detectors, and has automated mapping capability.

When samples return to the lab

In order to get a concentration that can be analyzed easily by gas chromatography and mass spectrometry (GC/MS), samples are further concentrated to about 0.2 mL using a mini-evaporator.

From s study biodiversity in planktonic microorganisms.

From a biodiversity study in planktonic microorganisms. A result of a population model simulating the effects 30 competing species. Coexistence for at least 1000 generations was observed in at least 90% of the simulations when there were initially at least 1000 individuals
per species. No extinctions were observed.

The traveltime sensitivity kernels for the head wave on the horizontal planes at depths below and above the interface that separates the low and high velocity layers

The traveltime sensitivity kernels for the head wave on the horizontal planes at depths below and above the interface that separates the low and high velocity layers. The green line marks the head wave ray path. The source is located on the left side of this figure. The negative (red colors) and positive (blue colors) values are so defined that a low-velocity anomaly located in the region of the negative kernels results in a travel time delay and the same velocity perturbation in the region of positive kernels leads to an earlier head wave arrival.
