A scalable underwater sensor for dissolved inorganic carbon
Abstract: There is no commercially available sensor in existence for measuring dissolved inorganic carbon (DIC) in-situ in the ocean, one of the key parameters needed for OVSN. We propose to overcome this challenge by developing a low cost in situ dissolved inorganic carbon (DIC) sensor for submersible ocean applications. The sensor will be small, inexpensive,…
Leveraging commercial ships for ongoing phytoplankton community observations
Productivity of photosynthetic plankton in the upper ocean is critical to the functioning of marine food webs and the ocean’s role in global carbon cycling. These phytoplankton are extremely diverse and respond rapidly to changes in the environment, so chronic undersampling continues to limit understanding of how natural variability and intentional perturbations in ocean conditions…
Establishing a glider-based biogeochemical observing network for the Gulf Stream
Abstract: A central challenge for the envisioned Ocean Vital Signs Network (OVSN) will be to capture the Gulf Stream’s impact on physical and biogeochemical budgets in the northwest Atlantic. Doing so will require measurements with high spatial resolution to capture sharp gradients, broad spatial coverage of the Gulf Stream and its associated eddies and meanders,…
OVSN System Design
The Ocean Vital Signs Network System Design (OVSN SD) Team will advance OVSN modeling and data system priorities including (1) Skill assessment of current models and state estimates (2) data platform design and implementation (3) advancing regional numerical modeling of the Northwest Atlantic and (4) Model-based assessment for planning regional-scale observing strategies. The team will…
