String summary "This dataset provides water column environmental data for a study that explored the relationships between glacial meltwater-modified ocean circulation, iron supply, and pelagic bacterial community structure in the Amundsen Sea polynya (ASP), Antarctica. Onboard the RVIB Nathaniel B. Palmer, cruise NBP 22-02, January–March 2022, we examined particle-associated (3-micrometer (µm) polycarbonate pre-filter) and free-living (0.2 µm Durapore filter) bacterial 16S rRNA in seawater from 21 stations (at depths from 2 to 1271 meters (m)) in the context of a suite of ocean observations along the \"iron conveyor belt.\" This key circulation pathway follows Circumpolar Deep Water cascading from the Antarctic Circumpolar Current, along the bottom of the fore-deepened continental shelf toward the deep ice shelf cavity, where it melts the base of the ice shelf, then buoyantly upwells via meltwater entrainment, and delivers iron-rich waters to the surface waters of the polynya. A coastal current also transports this and other meltwater-rich outflows from east to west, and may play an important role in fueling ecosystem production. We were able to sample key water masses: Antarctic Surface Water (AASW), Winter Water (WW), Circumpolar Deep Water (CDW), and modified/mixed variants. Measured environmental parameters in this dataset are CTD variables (temperature, salinity, pressure, dissolved oxygen, beam transmissivity, fluorescence), macronutrients (nitrate, nitrite, ammonium, phosphate), lab chlorophyll a, micronutrient dissolved iron, δ¹⁸O, and calculated meltwater fractions. Results from this dataset, combined with 16S rRNA amplicon data, revealed distinct bacterial communities, characterized by location within the ASP, suggesting community succession along the route.";

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
