Dataset: Nutrient concentrations from R/V Pelican cruise PE21-18 in the Northern Gulf of Mexico in April and May 2021

Sampling was conducted on R/V Pelican cruise PE21-18 in the Northern Gulf of Mexico during April-May 2021. Surface and bottom water samples were collected in duplicate at five stations.

Duplicate water samples from surface and bottom water at each station were collected from Niskin bottles attached to the CTD rosette into polycarbonate carboys and subsequently filtered via peristaltic pumping and masterflex tubing through 2.7 µm Whatman GF/D and 0.22 µm Sterivex filters. This filtrate was collected into 50 mL Falcon tubes and immediately stored at -20 degrees Celsius. Samples were shipped frozen to the University of Washington Marine Chemistry Laboratory for analysis.
