After enjoying the California sunshine in San Francisco Bay, NOAA Ship Fairweather began its transit down the coast towards Santa Barbara, California. The ship would not anchor for the next sixteen days, leaving all crew on 24-hour rotations. Thankfully, the already attenuated crew was visited by augmenting scientists and hydrographers – Physical Scientist Devereaux from the Pacific Hydrographic Branch, HHST Arboleda from NOAA Ship Thomas Jefferson, and HAST Schrader from NOAA Ship Rainier. Together, they traveled south to complete one of the last projects of the season, the area in and around Channel Islands National Marine Sanctuary.

After six months of surveying in Alaska, NOAA Ship Fairweather was ready to point the bow south and set sail for San Francisco Bay. However, an unforeseen circumstance stymied the planned underway date. Although we eagerly anticipated the warmer waters of San Francisco Bay, this delay was well received by the hydrographers in the survey department and amongst the NOAA Corps officers. Our work had begun stacking up due to an extremely busy season, coupled with the fact that for most of us, this was our first time working on hydrographic project sheets. Therefore, we happily used this week of “down-time” to complete previous project sheets and plan for the upcoming survey. Those of us as sheet managers focused on cleaning multibeam data, processing backscatter mosaics, attributing features, conducting quality control checks, and writing descriptive reports. This process was greatly assisted with the help of augmenting physical scientists Pete Holmberg and Janet Hsiao. In the end, we were able to finish processing a number of sheets and reach a comfortable place on all the others. After a week of long hours, we were finally ready to toss lines and say “see you next year Alaska.”
