Description
NOAA_NCEI collected near-surface oceanographic and atmospheric data using three Saildrone autonomous surface vehicles in the eastern Bering Sea and northern Pacific Ocean from June to August 2020. The dataset includes measurements of water temperature, salinity, chlorophyll-a, dissolved oxygen, wind, air temperature, humidity, and air pressure. This experimental survey was conducted as an alternative to a canceled ship-based walleye pollock acoustic survey.
Use Cases
Analyze correlations between chlorophyll-a measurements from the fluorometer and acoustic survey data for walleye pollock habitat modeling.
Model sea surface skin temperature gradients using SST IR pyrometer data alongside water temperature from the thermosalinograph.
Study air-sea interactions by comparing wind speed and direction from the anemometer with concurrent water temperature and salinity readings.
Assess dissolved oxygen concentrations from the oxygen optode across the survey's 14 transects spanning the 80m to 1000m depth contour.
Strengths
Data collected from three distinct autonomous vehicles (Saildrones 1043, 1046, 1049) over a two-month period.
Covers 14 survey transects spaced 74 km apart across a significant depth gradient from ~80m to ~1000m.
Limitations
Data are experimental and explicitly stated as not quality controlled, requiring user validation.
Limited temporal coverage to a single summer season (2020), restricting long-term trend analysis.
Echosounder data for the primary walleye pollock survey is archived separately and not included here.
