The MarineFlux project aims to establish a user-friendly web access point for the dissemination of turbulent air-sea fluxes and the essential ocean and climate variables (EOV/ECV) required to estimate the fluxes from surface in-situ platforms. The service presently includes fluxes derived from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS), the Shipboard Automated Meteorological and Oceanographic Systems (SAMOS) initiative, and select flux datasets from NOAA expeditionary cruises. In addition to flux observations, MarineFlux strives to include extensive metadata to support discovery, search, access, and application for a wide range of users. The primary data access service supported by MarineFlux is ERDDAP. Additionally, MarineFlux provides an interactive data visualization tool, the MarineFlux Explorer, to support analysis of the in-situ observations alongside select satellite datasets.
