Carbonate System data on Georges Bank from cruises occurring in May and September 2021

Abstract

These data are described in a study presenting the first high-resolution spatial analysis of carbonate chemistry on Georges Bank, a highly productive shallow bank located at the southeastern edge of the Gulf of Maine. Despite numerous studies on the hydrography, nutrient chemistry, and biology, regional carbonate chemistry remains unexplored, in particular for near-bottom conditions. Data included in this repository were collected during two cruises that occurred in May and October 2021. Data include temperature, salinity, pressure, dissolved oxygen, dissolved inorganic carbon, and total alkalinity. These data were used to identify multi-endmember mixing, and the manuscript describes the result of a Bayesian mixing model analysis that separates water mass mixing from other processes like net community production, air-sea exchange, and other biogeochemical processes/error. Data included in this repository were collected during two cruises that occurred in May and October 2021 on Georges Bank, in the Northwest Atlantic region. Data include surface and bottom water temperature, salinity, pressure, dissolved oxygen, dissolved inorganic carbon, and total alkalinity.
