Data is collected from the CTD deployed at various stations. This record descripbes three datafiles. (1) POC_data: station, pressure, temperature, conductivity, salinity, PAR, total beam attenuation coefficients (c), attenuation by particles (cp), site, particulate organic carbon concentration (from optical measurements), rho, longitude and latitude. (2) Ammonium: station, pressure, site, ammonium, latitude, longitude (3) POC_PON_ratio: site, depth, particulate organic carbon concentration (measured) particulate organic nitrogen concentration (measured), C:N ratio. {"type": "Polygon", "coordinates": [[[119.0, -68.0], [148.0, -68.0], [148.0, -61.0], [119.0, -61.0], [119.0, -68.0]]]} 119.0 148.0 -68.0 -61.0 Niskin bottle deployed from CTD Photosynthetically active radiation (PAR) DATA ACCESS - POC data (optical sensor), and PON/POC data from CTD bottles [file browse] documentDigital HTML imas:ACE_Ratnarajah_AntarcticCTD_POC documentDigital MAP - CTD sampling locations (POC from optical sensor) WMS imas:ACE_Ratnarajah_AntarcticCTD_POC_PON documentDigital MAP - CTD sampling locations with Niskin collected for POC and PON sampling WMS imas:ACE_Ratnarajah_AntarcticCTD_Ammonium documentDigital MAP - CTD sampling locations with Niskin collected for Ammonium sampling WMS imas:ACE_Ratnarajah_AntarcticCTD_POC documentDigital OCG WFS service for data (POC from optical sensor) WFS imas:ACE_Ratnarajah_AntarcticCTD_POC_PON documentDigital OGC WFS service for data (POC:PON ratios from Niskin water sample) WFS imas:ACE_Ratnarajah_AntarcticCTD_Ammonium documentDigital OCG WFS service for data (Ammonium from Niskin water sample) WFS View and download this data through the interactive IMAS Data Portal. documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
