Seawater was collected on board the NOAA ship Ronald H. Brown as part of the fourth Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC-4) cruise from September 13 to October 21, 2021. Sampling for GOMECC-4 occurred along 16 coastal-offshore transects across the entire Gulf of Mexico and an additional line at 27N latitude in the Atlantic Ocean. We also collected eDNA samples near Padre Island National Seashore (U.S. National Parks Service), a barrier island located off the coast of south Texas. Vertical CTD sampling was employed at each site to measure discrete chemical, physical, and biological properties. Water sampling for DNA filtration was conducted at 54 out of 141 total sites and three depths per site (surface, deep chlorophyll maximum, and near bottom) to capture horizontal and vertical gradients of bacterial, protistan, and metazoan diversity across the Gulf.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 311,390 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Project Data

The effort was in support of the coastal monitoring and research objectives of NOAA’S Ocean Acidification Program. The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. This was the fourth occupation of the Gulf of Mexico as part of the Ocean Acidification Program’s monitoring efforts, with the first three occurring in 2007, 2012 and 2017.

Study Area Description This report describes the fourth Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC4) cruise on board the R/V Ronald H. Brown departing from Key West, FL into the Gulf of Mexico and then around the coastal waters of the Gulf of Mexico in a counter-clockwise direction. The cruise took place from September 13–October 21, 2021
Design Description The cruise included a series of 15 transects approximately orthogonal to the coast of the Gulf of Mexico and a 16th partial transect along the 27°N line, between Florida and the Bahamas, as well as a comprehensive set of underway measurements along the entire cruise track. In addition to these transects, three more stations were sampled as part of a collaboration with the National Parks Service to monitor ocean acidification at national parks. Four parks participated in this effort: Padre Island (in Texas), Dry Tortugas, Everglades, and Biscayne (these three in Florida).
