Cetacean visual observations using line-transect survey methods onboard the NOAA Ship Gordon Gunter (GU) in the Gulf of Mexico, for the Vessel Surveys for Abundance and Distribution of Marine Mammals and Seabirds project (VSAD survey GU2402) from 2024-06-03 to 2024-08-12 (NCEI Accession 0299731)

Description

As part of the Vessel Surveys for Abundance and Distribution of Marine Mammals and Seabirds (VSAD) project, the Southeast Fisheries Science Center (SEFSC) conducted a shipboard survey of the U.S. oceanic waters of the Gulf of Mexico out to the Exclusive Economic Zone (EEZ) from 2023-06-22 to 2023-08-14. The survey was designed for a two-team independent visual observer approach with distance sampling to estimate the detection probabilities for marine mammal sightings. A sighting constituted a single or group of marine mammals (whales and dolphins) seen at the same location and time. This dataset includes marine mammal visual observation data and effort points with surveying conditions that can be used in abundance and density modeling per visual line-transect survey protocols. This dataset also includes opportunistic marine mammal photographs and biopsy samples, and non-marine mammal sightings (a.k.a. occurrences) such as sea turtles.

Darwin Core Extended Measurement Or Fact Issued 2023-08-28 XML Support for generic measurements or facts, extended version linking to occurrences. This extension (eMoF) was developed to be used in combination with the Event Core, but is also compatible with other cores. When used with Event Core it allows to create an additional link between the eMoF and the occurrence extension. The eMoF can store measurements or facts related to a biological occurrence, environmental measurements or facts and sampling method attributes. This extension also provides the option to provide identifiers to reference a vocabulary for the measurementType, measurementValue and measurementUnit fields Open resource
