EXport Processes in the Ocean from RemoTe Sensing (EXPORTS)

EXPORTS is a scoping study for a major NASA field campaign to quantify the state of the ocean biological pump from satellite observations. This session included a brief overview of the EXPORTS science plan and its role in NASA planning, followed by a series of talks that highlight the three overarching science questions in the plan. Currently, a science definition team is developing a detailed implementation plan for the EXPORTS field campaign. Following the science presentations, a brief overview of the draft EXPORTS implementation plan was presented, with plenty of time thereafter for discussion.

The Biology of Carbon Export: New Processes and Approaches

NSF recently sponsored a workshop to foster discussions around new perspectives and identify critical gaps in our understanding of key biological processes involved in ocean carbon export. This session included a brief overview of the workshop, its outcomes, and its role in NSF planning (see white paper entitled Towards a transformative understanding of the ocean’s biological pump: Priorities for future research, followed by a short series of science talks highlighting some of the biologically mediated processes that emerged from workshop discussions.

Recent Advances in Quantifying Ocean Carbon Uptake

This session highlighted exciting new research developments on ocean carbon uptake across spatial (coastal to open ocean) and temporal (paleoclimate to future climate scenarios) scales. Plenary speakers addressed advances in observation and modeling, including new approaches to estimating interannual variability in CO2 uptake using interpolated data, as well as new ensemble modeling approaches that estimate the time of emergence in ocean carbon uptake trends against the backdrop of natural variability.

Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM): A Prototype for a Global Biogeochemical-Argo Array

SOCCOM has ~50 profiling floats with oxygen, pH, nitrate, and bio-optical sensors in all regions of the Southern Ocean from seasonal ice zones to the open ocean, and the array will grow to ~200 floats in several years. In this session, we’ll describe work in progress to analyze the annual cycles of carbon, oxygen, nitrate, and chlorophyll observed by the sensors and efforts to integrate the data with numerical models. Finally, we’ll report on work to develop the science and implementation plan for a global observing system based on profiling floats with biogeochemical sensors.

The Indian Ocean: Monsoon-Driven Biogeochemical Processes

The monsoonal forcing of the Indian Ocean makes it a unique oceanic basin that is subject to semi-annual reversals of its boundary currents, stark contrasts in buoyancy forcing between the Arabian Sea and Bay of Bengal, as well as semi-annual manifestation of the zonal, cross-basin equatorial Wyrtki Jets. Connectivity with the Pacific Ocean via the Indonesian Throughflow introduces further dynamical complexity to the Indian Ocean basin. In celebration of the 50th anniversary of the International Indian Ocean Expedition (IIOE) and launch of the IIOE-2, this plenary session focused on how these complex physical oceanographic and climatic drivers influence biogeochemistry and biological processes in this ocean basin.

Marine Ecosystem Thresholds and Regime Shifts

Marine ecosystem regime shifts have been observed in many locations and periods around the global ocean, and more regime shifts may occur as key anthropogenic stressors change in the coming years to decades. However, the drivers of marine ecosystem regime shifts remain poorly understood, as are their consequences for biogeochemical cycles and the management of marine resources. In this session, we document key examples of marine ecosystem regime shifts and examine their likely causes, as well as discuss the impacts of regime shifts on biogeochemical cycles and the management of altered ecosystems.

ARCTIC-COLORS Workshop

Thursday, July 28-Friday, July 29 (Woods Hole Oceanographic Institution)

Organizers: Antonio Mannino (NASA GSFC), Maria Tzortziou (CUNY)

Arctic-COLORS (Arctic-COastal Land Ocean inteRactions) is a Field Campaign Scoping Study supported by NASA’s Ocean Biology and Biogeochemistry (OBB) Program that aims to quantify present and future impacts of changing land and ice on marine net ecosystem productivity in the fastest warming environment on the planet: the Arctic. A Science Plan is under development that describes and justifies the design of an integrative, interdisciplinary oceanographic field campaign and modeling program that addresses high priority science questions related to land-sea-ice interactions in the nearshore Arctic, and assesses the impacts of natural and anthropogenic changes on coastal ocean ecology and biogeochemistry.

The panel convened by NASA OBB to review a preliminary version of the Arctic-COLORS Science Plan was very supportive of Arctic-COLORS and recommended revisions and re-submission of the report for further consideration by NASA. Immediately following the OCB workshop, there was a 1.5-day open community workshop at WHOI (July 28-29) to engage interested scientists in a dialog about the proposed field campaign and obtain broad community input on these revisions. During this workshop we (1) focused on the top level science questions, (2) discussed potential de-scoping scenarios, and (3) narrowed the study domain.
