Latest Shipboard Observations (Hourly Update)

Shipboard sensors provide meteorological and oceanographic measurements for the marine environment. This information is made available through the National Data Buoy Center (NDBC) and this layer pulls updates direct from the NDBC hourly (at the top of the hour). The most recent observation data is made available for each of the reporting ships. This layer is time enabled, allowing access to recent historical observation data. Dataset Summary Phenomenon Mapped: Shipboard Observations (Meterological and Oceanographic) Geographic Extent: Global transiting vessels Layer Projection: World Geodetic System 1984 (WGS 1984) Time Extent: Most recent Update Frequency: Hourly Visible Scale: This layer performs well between scales of 1:50,000,000 to 1:1,000 Source: National Data Buoy Center NDBC Publication Date: June 15, 2026 This layer has a companion layer, National Data Buoy Center Station Observations (Hourly Update), showing meterological and oceanographic observations from stationary buoys in U.S. Territories. What can you do with this layer? NDBC data are commonly visualized and analyzed to provide spatial context for real-time conditions and decision support across marine, coastal, and ocean-related workflows. Questions? Please leave a comment below if you have a question about this layer, and we will get back to you as soon as possible.
