A quantitative comparison of the physical supply and biological uptake of new nitrogen in the Arctic Ocean
Abstract Nitrogen constrains biomass across the Arctic Ocean, with nitrate (NO3) supply to the surface waters fuelling new primary production and net carbon drawdown. In this Review, we explore the physical mechanisms driving NO3 fluxes to the euphotic zone across the Arctic Ocean and how biological processes respond. The volume and inflow depth of Atlantic and Pacific Ocean waters, together with sea ice and halocline dynamics, govern internal physical mixing of NO3.
Scientists sailed from Antarctica to the equator to study the ‘ocean’s gut bacteria’
Bacteria can help researchers measure shifts in energy production in the ocean. This can help them assess ecosystems in different marine enivronment. This kind of information can help us better understand the impact of a changing climate on complex ecosystems. Aboard an Australian research vessel, the RV Investigator, we sailed for 63 days from Antarctica’s ice edge to the warm equator in the South Pacific and collected 387 water samples. Our goal?
The ocean's 'gut flora': How bacteria affect ocean health from Antarctica to the equator
Marine bacteria provide the energy and food for the entire marine food web, from tiny crustaceans to whales.

Like the ocean’s ‘gut flora’: we sailed from Antarctica to the equator to learn how bacteria affect ocean health
Aboard an Australian research vessel, the RV Investigator, we sailed for 63 days from Antarctica’s ice edge to the warm equator in the South Pacific and collected 387 water samples. Our goal? To determine how the genetic code of thousands of different micro-organisms can provide insights into the ocean’s functional diversity — the range of tasks performed by bacteria in the ocean. Our research was published yesterday in Nature Communications.
Production and ecosystem structure in cold‐core vs. warm‐core eddies: Implications for the zooplankton isoscape and rock lobster larvae - Waite - - Limnology and Oceanography - Wiley Online Library
Abstract Anticyclonic (warm‐core) mesoscale eddies (WCEs) in the Eastern Indian Ocean carry higher surface chlorophyll signatures than cyclonic (cold‐core) eddies (CCEs). Paradoxically, WCEs host rock lobster larvae (phyllosomas) with lower lipid stores and protein reserves than phyllosomas in CCEs, suggesting a poorer nutritional status.
