Purpose

These scripts create daily survey station daily temperature and anomaly plots as the ships work their way through the Bering Sea. These ships are conducting NOAA Fisheries’ Alaska Fisheries Science Center’s fisheries independent surveys in the Eastern Bering Sea. Scripts pull temperatures from google drive, entered by FPCs at sea, create daily maps and composite gifs, and then push the maps to google drive for the communications team. These plots are displayed on the AFSC website

NOAA Fisheries AFSC Groundfish Assessment Program conducted the Aleutian Islands bottom trawl survey. The near real-time ocean bottom temperatures depicted were collected June 7-June 21 On June 21, stations 237-36 (52.52°N, -172.26°W; >3.5–4°C), 236-36 (52.52°N, -172.34°W; >4–4.5°C), and 238-37 (52.57°N, -172.18°W; >3.5–4°C) were surveyed by the F/V Ocean Explorer. No stations were surveyed by the F/V Alaska Provider.

Updated colors: This year in an effort to make the heatmaps more accessible to a broader audience a new color scheme was used for our heatmaps. However, given feedback we have received we are reverting back to the colors used in previous years.

The near real-time ocean bottom temperatures depicted were collected June 2-June 21 On June 21, stations K-04 (58.33°N, -165.88°W; >2–3°C), L-04 (58.67°N, -165.89°W; >2–3°C), and M-04 (59°N, -165.9°W; >3–4°C) were surveyed by the F/V Alaska Knight and stations K-05 (58.33°N, -165.24°W; >2–3°C), K-06 (58.33°N, -164.61°W; >2–3°C), and L-05 (58.67°N, -165.25°W; >2–3°C) were surveyed by the F/V Northwest Explorer. There are 8 stations planned for June 22 Credit: NOAA Fisheries
