Microbial respiration in contrasting ocean provinces via high-frequency optode assays Open
Microbial respiration is a critical component of the marine carbon cycle, determining the proportion of fixed carbon that is subject to remineralization as opposed to being available for export to the ocean depths. Despite its importance, …

A Gulf Stream frontal eddy harbors a distinct microbiome compared to adjacent waters Open
Mesoscale oceanographic features, including eddies, have the potential to alter productivity and other biogeochemical rates in the ocean. Here, we examine the microbiome of a cyclonic, Gulf Stream frontal eddy, with a distinct origin and e…

Microbial Respiration in Contrasting Ocean Provinces via High-Frequency Optical Assays Open
Microbial respiration plays a pivotal role in the marine carbon cycle, influencing the fraction of fixed carbon that undergoes remineralization versus export to depth. Despite its importance, methodological constraints have led to an inade…

Primary production dynamics during the decline phase of the North Atlantic annual spring bloom Open
The second field campaign of the NASA EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) program was conducted in the late spring of 2021 within the vicinity of the Porcupine Abyssal Plain (49.0°N, 16.5°W) in the North Atlantic Oc…

The Impact of Gulf Stream Frontal Eddies on Ecology and Biogeochemistry near Cape Hatteras Open
Ocean physics and biology can interact in myriad and complex ways. Eddies, features found at many scales in the ocean, can drive substantial changes in physical and biogeochemical fields with major implications for marine ecosystems. Mesos…
View article: Evaluation of new and net community production estimates by multiple ship-based and autonomous observations in the Northeast Pacific Ocean
Evaluation of new and net community production estimates by multiple ship-based and autonomous observations in the Northeast Pacific Ocean Open
New production (NP) and net community production (NCP) measurements are often used as estimates of carbon export potential from the mixed layer of the ocean, an important process in the regulation of global climate. Diverse methods can be …

Phytoplankton size-class contributions to new and regenerated production during the EXPORTS Northeast Pacific Ocean field deployment Open
The NASA EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) program was established to better quantify the pathways of the biological carbon pump in order to gain a more comprehensive understanding of global carbon export efficien…

An operational overview of the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) Northeast Pacific field deployment Open
The goal of the EXport Processes in the Ocean from RemoTe Sensing (EXPORTS) field campaign is to develop a predictive understanding of the export, fate, and carbon cycle impacts of global ocean net primary production. To accomplish this go…

Brightly coloured tissues in limid bivalves chemically deter predators Open
Members of the marine bivalve family Limidae are known for their bright appearance. In this study, their colourful tissues were examined as a defence mechanism towards predators. We showed that when attacked by the peacock mantis shrimp ( …
