Processed CTD Data from Deepwater Horizon Oil Spill Response

Conductivity Temperature Depth (CTD) measurements were collected aboard the R/V Ocean Veritas 01 to determine physical oceanographic parameters in the Gulf of Mexico. The dataset contains processed and quality-checked casts with parameters including temperature, conductivity, salinity, depth, dissolved oxygen, and fluorometry. It was created by NOAA NCEI as part of the Deepwater Horizon oil spill Natural Resource Damage Assessment (NRDA) sampling effort.

Use Cases

• Analyzing vertical profiles of water column properties like temperature and salinity using CTD cast data.
• Investigating dissolved oxygen levels and fluorometry signals related to oil spill impacts.
• Mapping spatial oceanographic conditions in the Gulf of Mexico using latitude and longitude coordinates from the cruise.
• Supporting Natural Resource Damage Assessment (NRDA) by providing baseline physical data for the affected region.

Strengths

• Data has been processed and undergone quality checking, as stated in the platform descriptions.
• Contains multiple key oceanographic parameters: temperature, conductivity/salinity, depth, dissolved oxygen, and fluorometry.
• Associated with a major environmental event (Deepwater Horizon oil spill), providing context for analysis.

Limitations

• The exact number of rows, columns, and file size is unknown across all sources.
• There is a conflict in the 'last updated' metadata: one source states 2004-05-30, while another states 2026-03 06.
