Release Notes

Known Issue

We are generating some Entry Events that are unlikely to reflect real vessel movements. While we are not certain what is driving these transmissions —AIS can be noisy or inconsistent for many reasons—it appears that our current filtering of AIS message is not handling these as effectively as before. Regardless of the cause we plan to improve filtering to reduce noise and minimize false positives.

June 13, 2025

  • Added deep link to SkyTruth Cerulean on the vessel details page for vessels potentially associated with oil slick, as indicated by Cerulean.

June 2, 2025

  • The GFW vessel filters from May 28 release integrated with Saved Filters 
  • Added estimated attributes for Sentinel-2 vessel detections (Estimated Length, Speed, Heading, Type)
  • Added filter for estimated length on Commercial Optical and Sentinel-2 imagery

May 28, 2025

  • Integrated the Global Fishing Watch (GFW) Vessel API such that:
    • It is possible to filter events on Gear Type, Authorization Lists, Owner Name, and Owner Flag
    • The GFW data on the Vessel Details Page references this API (data refreshed every week)  
  • Updated event details cards to show when AIS and GFW data differs
  • Rounded coordinates & timestamps in downloaded event data
  • Fixed French translations on vessel details page
  • Fixed issue where Standard Rendezvous events would show up as “undefined - undefined” when the vessel name was not known

May 12, 2025

  • Improvements to how Port Visits, Speed Range Events, and Entry Events are calculated so they are faster and more accurate. 

May 1, 2025

  • Unhid referral information to Global Fishing Watch from Skylight Vessel Details Page 

April 24, 2025 

  • Re-running AIS correlation on satellite imagery every 3 hours (instead of once a day). This should cause un-correlated detections for which we later get AIS data to get correlated faster

April 21, 2025

  • Started processing inland lakes 
  • Estimated lengths and heading for Sentinel-2 in production 

January 24, 2025 

  • Create areas (AOIs) workflow improved in user interface 
  • Allow pasting MMSIs from Google Sheet into MMSI filter
  • French localization updates 
  • New filters for vessel detections by satellite source
  • Update tip & cue to save satellite tips in a database (no user impact) 
  • Updated how events are called from GraphQL API (no user impact) 

December 12, 2024

  • New vessel details page with event and track map including time slider
  • Bug fix for users blocked from accepting terms and conditions

December 10, 2024

  • Deprecated “in progress” event filter

November 27, 2024

  • Rendezvous track color and border in baseball card match
  • Fix bug where event icons appear overlayed on heatmap

November 20, 2024

  • Added “Show All Tracks” feature
  • Improved rendezvous generation for vessel-to-vessel events (reduce false positives from buoys)
  • “My Skylight” menu updates
  • Map tile loading progress indicator

November 4, 2024

  • Optical Imagery from Landsat 8,9 now available in the KML network link 
  • Vessel type for SAR updated to “Search and Rescue”
  • Other bug fixes

October 16, 2024

  • Performance updates to reduce long load times (15% load time reduction)

October 10, 2024

  • Updated Fishing Model under new architecture to greatly improve latency and accuracy.

September 27, 2024

  • Vessel detection from Landsat 8/9 added.

September 12, 2024

  • New GraphQL API documentation.

September 10, 2024

  • Add 3rd VIIRS satellite (NOAA-21).  And a total overhaul of the viirs pipeline to make it faster and more error resilient.
  • Time slider added 
  • Improved track visualization, including updated legend 
  • Other bug fixes
