Atlantic Sturgeon Risk of Encounter


This product is developed for mature Atlantic Sturgeon using historic telemetry observations matched to date, bathymetry, and sea surface temperature and ocean color from NPP-VIIRS satellite. There are five regions (Delaware River, Upper Delaware Bay, Middle Delaware Bay, Lower Delaware Bay, and Atlantic Ocean) and each of them is divided into 5 meter depth bins.

NOTE: The SNPP-VIIRS satellite this product uses is experiencing geolocation issues. Data will be delayed and the model results will be suspect until further notice

Encounter Risk:

-- Green = Low Risk -- Yellow = Medium Risk -- Red = High Risk

Climatologies of Sea Surface Temperature, Atlantic Sturgeon Model Predictions, and Atlantic Sturgeon Risk Categories based on an average conditions for each calendar day from 2003-2017 MODIS-Aqua satellite data (15 years). Atlantic sturgeon model predictions greater than 0.01 should be treated as likely presence (Medium Risk) of Atlantic Sturgeon. Values greater that 0.05 are considered High Risk of Atlantic Sturgeon presence
