|At each FISS station, oceanographic equipment is deployed to capture the water column profile prior to retrieving the longline gear. Water column profiles include chlorophyll a and pH, in addition to temperature, depth, salinity, and dissolved oxygen concentration. These data are processed and made available via collaboration with the JISAO (Joint Institute for the Study of the Atmosphere and Ocean) at the University of Washington and NOAA’s Pacific Marine Environmental Laboratory.

Commercial Sex-Marking Data
|In 2014, the IPHC initiated a project intended to lead to direct observation of sex as a routine element of its ongoing Port Sampling program. The project includes at-sea sex-marking in the directed longline fishery, to be accompanied by genetic methods to validate the sex-marking.

|Data collected on our surveys can be viewed at the OBIS-SEAMAP (Ocean Biogeographic Information System Spatial Ecological Analysis of Megavertebrate Populations) site of Duke University.

NOAA Fisheries Groundfish Trawl Surveys
The IPHC partners with the National Oceanic and Atmospheric Administration to collect Pacific halibut data during their groundfish bottom trawl surveys conducted in the summer months. The Bering Sea is surveyed annually and both the Gulf of Alaska and Aleutian Islands are surveyed biennially. Summaries of Pacific halibut data collection and results on the trawl surveys are provided here, and within each summary are links to additional information and data.
