Projected Changes in Photosynthetic Picoplankton in a Warmer Subtropical Ocean

Frontiers in Marine Science, 2019
The oligotrophic subtropical gyres are the largest biome on Earth, where picoplankton constitute the dominant autotrophs. The trend for autotrophic picoplankton to increase with sea temperature has led to predictions that picophytoplankton abundance will

Scratching Beneath the Surface: A Model to Predict the Vertical Distribution of Prochlorococcus Using Remote Sensing

Remote Sensing, 2018
The unicellular cyanobacterium Prochlorococcus is the most dominant resident of the subtropical gyres, which are considered to be the largest biomes on earth.

Sorption of PCBs to environmental plastic pollution in the North Atlantic Ocean: Importance of size and polymer type

Case Studies in Chemical and Environmental Engineering, 2020
Plastic pollution is a great threat to the marine environment. Owing to its low density, a substantial fraction of plastic debris is transported across ocean surfaces by currents.

Eddy Cancellation of the Ekman Cell in Subtropical Gyres

Journal of Physical Oceanography, 2016
AbstractThe presence of large-scale Ekman pumping associated with the climatological wind stress curl is the textbook explanation for low biological activity in the subtropical gyres. Using an idealized, eddy-resolving model, it is shown that Eulerian-mean Ekman pumping may be opposed by an eddy-driven circulation, analogous to the way in which the ...

Proteorhodopsin variability and distribution in the North Pacific Subtropical Gyre [PDF]

The ISME Journal, 2018
Abstract Proteorhodopsin is a light-activated retinal-containing proton pump found in many marine bacteria. These photoproteins are globally distributed in the ocean’s photic zone and are capable of generating a proton motive force across the cell membrane.

Barrier layer in the North Pacific subtropical gyre [PDF]

Geophysical Research Letters, 2004
By analyzing all the available temperature/salinity profiles obtained by Argo floats as of August 2003, we evaluate the barrier layers (BLs) in the North Pacific subtropical gyre. 20.5% of the profiles at 10°–25°N have BLs with thickness greater than 10 m.

Chlorophyll Variability in the Oligotrophic Gyres: Mechanisms, Seasonality and Trends

Frontiers in Marine Science, 2015
A 16-year (1998-2013) analysis of trends and seasonal patterns was conducted for the five subtropical ocean gyres using satellite data: chlorophyll-a (Chl-a) retrievals from ocean color, sea surface temperature (SST), and sea-level anomaly (SLA).

Meridional transport of salt in the global ocean from an eddy-resolving model [PDF]

Ocean Science, 2014
The meridional transport of salt is computed in a global eddy-resolving numerical model (1/12° resolution) in order to improve our understanding of the ocean salinity budget. A methodology is proposed that allows a global analysis of the salinity balance

Resonantly Forced Baroclinic Waves in the Oceans: A New Approach to Climate Variability

Journal of Marine Science and Engineering, 2020
How variations in Earth’s orbit pace the glacial-interglacial cycles of the Quaternary are probably one of the greatest mysteries of modern climate science.

Dissolved organic carbon dynamics in a changing ocean: an ESM2M-COBALTv2 coupled model analysis [PDF]

Biogeosciences
Dissolved organic carbon (DOC) constitutes a major component of the marine carbon cycle, yet its present contributions to carbon export, and the response to future climate change remain poorly constrained.
