Who’s eating whom in the planktonic food web of the Northeast Shelf?

It is critical to quantify the amount of phytoplankton that microzooplankton consume to better understand the flow of carbon toward higher trophic levels in the ocean. The Northeast US Shelf (NES) sustains intense fisheries with huge economical importance, but the links between the planktonic food web and the fish stocks are poorly constrained. A recent […]

Integrated Ocean Carbon Research New Report

Integrated Ocean Carbon Research: A Summary of Ocean Carbon Knowledge and a Vision for Coordinated Ocean Carbon Research (IOC-R) and Observations for the Next Decade The UN Educational, Scientific and Cultural Organization (UNESCO)’s Intergovernmental Oceanographic Commission (IOC) has just published the “Integrated Ocean Carbon Research: A Summary of Ocean Carbon Knowledge and a Vision for […]

Register now: GO-BCG workshop

Virtual Workshop on the New Global Ocean Biogeochemistry (GO-BGC) Array – Building a Community of Biogeochemical Float Data Users The Global Ocean Biogeochemistry (GO-BGC) array is a 5-year effort funded by the US National Science Foundation to produce and deploy 500 profiling floats equipped with biogeochemical sensors in the world ocean. Deployments will begin in […]

Taxonomic and nutrient controls on phytoplankton iron quotas in the ocean

The uptake of iron by phytoplankton is a key part of the marine iron cycle, but we still have a rudimentary understanding of the controls on this process. It is generally assumed that dissolved iron availability controls phytoplankton iron. Combining data from the GP16 GEOTRACES section and three other GEOTRACES-compliant cruises in the eastern Pacific, […]

Compilation of dissolved organic matter (DOM) data obtained from global ocean observations from 1994 to 2020

This compilation consists of measurements of dissolved organic matter (DOM) and other chemical and hydrographic parameters obtained during the global ocean observations from 1994-01-01 to 2019-12-31. Measurements of dissolved organic matter (DOM) in the open ocean have increased greatly since the late 1980’s, spurred by the growth in scientific interest directed at the ocean carbon […]

Community survey: Use of CO2-in-seawater reference materials

The U.S. Interagency Working Group on Ocean Acidification is engaging in efforts to increase the resilience of the production and distribution of reference materials for the quality control of measurements of seawater CO2 system parameters. Currently, there is a single source of reference materials for total alkalinity, dissolved inorganic carbon, and pH in seawater and […]

Register now for virtual OCB2021

We are excited to present an interactive series of events with early career activities,interactive panel discussions, virtual poster sessions, and opportunities for networking and socializing throughout the month of June. The OCB SSC has been busy for several months planning plenary sessions for this year’s workshop. This year, for each plenary session, the plenary talks […]

Acidity across the interface from the ocean surface to sea spray aerosol

The pH of aerosols controls their impact on climate and human health. Sea spray aerosols are one of the largest sources of aerosols globally by mass, yet it has been challenging to measure the pH of fresh sea spray aerosols in the past. A recent study published in PNAS measured sea spray aerosols under controlled […]
