Mechanisms of physical-biological-biogeochemical interaction at the oceanic mesoscale

DJ McGillicuddy Jr - Annual Review of Marine Science, 2016 - annualreviews.org
Mesoscale phenomena are ubiquitous and highly energetic features of ocean circulation.
Their influence on biological and biogeochemical processes varies widely, stemming not …

Microbial respiration, the engine of ocean deoxygenation

C Robinson - Frontiers in Marine Science, 2019 - frontiersin.org
Microbial plankton respiration is the key determinant in the balance between the storage of
organic carbon in the oceans or its conversion to carbon dioxide with accompanying …

The formation of a subsurface anticyclonic eddy in the P eru‐C hile U ndercurrent and its impact on the near‐coastal salinity, oxygen, and nutrient distributions

S Thomsen, T Kanzow, G Krahmann… - Journal of …, 2016 - Wiley Online Library

Nitrogen and oxygen isotopic studies of the marine nitrogen cycle

KL Casciotti - Annual review of marine science, 2016 - annualreviews.org
The marine nitrogen cycle is a complex web of microbially mediated reactions that control
the inventory, distribution, and speciation of nitrogen in the marine environment. Because …

Open ocean dead zones in the tropical North Atlantic Ocean

J Karstensen, B Fiedler, F Schütte, P Brandt… - …, 2015 - bg.copernicus.org
Here we present first observations, from instrumentation installed on moorings and a float, of
unexpectedly low (< 2 μmol kg− 1) oxygen environments in the open waters of the tropical …

Global observations of submesoscale coherent vortices in the ocean

D McCoy, D Bianchi, AL Stewart - Progress in Oceanography, 2020 - Elsevier
Subsurface-intensified anticyclones are ubiquitous in the ocean, yet their impact on the large-
scale transport of heat, salt and chemical tracers is poorly understood. These submesoscale …

Implications of nitrate and nitrite isotopic measurements for the mechanisms of nitrogen cycling in the Peru oxygen deficient zone

KL Casciotti, C Buchwald, M McIlvin - Deep Sea Research Part I …, 2013 - Elsevier
Oceanic oxygen deficient zones (ODZs) are important regions for oceanic primary
productivity, nitrous oxide (N 2 O) production, and the marine nitrogen (N) budget. These …

Biogeochemical role of subsurface coherent eddies in the ocean: Tracer cannonballs, hypoxic storms, and microbial stewpots?

I Frenger, D Bianchi, C Stührenberg… - Global …, 2018 - Wiley Online Library
Subsurface eddies are known features of ocean circulation, but the sparsity of observations
prevents an assessment of their importance for biogeochemistry. Here we use a global …

On the role of mesoscale eddies for the biological productivity and biogeochemistry in the eastern tropical Pacific Ocean off Peru

L Stramma, HW Bange, R Czeschel, A Lorenzo… - …, 2013 - bg.copernicus.org
Mesoscale eddies seem to play an important role for both the hydrography and
