Full Citation Examples
Large vessel surveys were conducted during the summer of 2009 and the winter of 2010 in the north-central Gulf of Mexico to examine the spatial distribution of sperm whales and to collect data on potential midwater prey. The vessel surveys included both visual and passive acoustic data collection to document the presence of sperm whales. Physical oceanographic data was collected to characterize the presence of eddies and other mesoscale physical features that have the potential to concentrate both sperm whales and their prey. Midwater trawls were deployed to collect specimens of midwater squids to identify likely prey items. These data are used to characterize the midwater prey community that supports sperm whale populations in the Gulf of Mexico.

| Abstract: |
Large vessel surveys were conducted during the summer of 2009 and the winter of 2010 in the north-central Gulf of Mexico to examine the spatial distribution of sperm whales and to collect data on potential midwater prey. The vessel surveys included both visual and passive acoustic data collection to document the presence of sperm whales. Physical oceanographic data was collected to characterize the presence of eddies and other mesoscale physical features that have the potential to concentrate both sperm whales and their prey. Midwater trawls were deployed to collect specimens of midwater squids to identify likely prey items. These data are used to characterize the midwater prey community that supports sperm whale populations in the Gulf of Mexico. |
| Purpose: |
To study the prey of sperm whales in the Gulf of Mexico. |
| Notes: |
A research cruise was conducted during January-March 2010 (Cruise number PI-10-01) which included targetted midwater sampling of potential prey of sperm whales feeding in the Gulf of Mexico. Data include visual survey, passive and active acoustics, sam |

Data Quality
| Quality Control Procedures Employed: |
Visual sightings are reviewed by lead observers and the field party chief at sea to verify species identifications and group size counts. Effort and sightings data from digital records are reviewed post-survey and compared to field notes and error logs. Corrected survey effort shapefiles are visually reviewed and verified. Species identifications for collected fish and squids were reviewed and verified by experts. |

Lineage
Process Steps
Process Step 1
| Description: |
Trackline, visual sightings, and passive acoustic data are collected using at-sea data collection programs. Field notes are recorded by observers and written onto paper datasheets which are then key entered into digital databases. Counts and measurements of collected fish and squids were recorded in the field. |
