MarineTraffic is an online vessel tracking platform providing AIS-based information on ship positions, movements and vessel characteristics, including draught information where available. Users can view individual vessels and their reported draught through the interactive map. This information can support vessel grounding risk assessment and Under Keel Clearance (UKC) analysis when combined with bathymetric data. Free access is limited to publicly displayed vessel information, while bulk data downloads and API services require additional access permissions or commercial arrangements.

The Harmonized Sentinel-2 MSI Level-2A (SR) collection provides wide-swath, high-resolution multispectral imagery for land and coastal monitoring. It contains Sentinel-2 Level-2A surface reflectance data, including 12 spectral bands at 10 m, 20 m and 60 m spatial resolutions. The harmonized collection adjusts newer Sentinel-2 scenes to maintain consistency with the value range of older scenes.

Landsat Collection 2 Level-2 Surface Reflectance products provide atmospherically corrected surface reflectance data derived from Landsat sensors. The products support analysis of changes in land surface conditions over time and provide a long-term record of multispectral Earth observations at 30 m spatial resolution.

The Sentinel-3 OLCI Level-2 Water Full Resolution (OL_2_WFR) product provides water and atmosphere geophysical parameters derived from OLCI observations at approximately 300 m spatial resolution. Water products include ocean-colour parameters such as chlorophyll and total suspended matter concentration, supporting the assessment of coastal and ocean water conditions.

Copernicus Sentinel-3 provides satellite observations of ocean and land colour, sea and land surface temperature, and sea surface topography. This record focuses on imagery and ocean-colour products available through the Copernicus Data Space Ecosystem. Spatial resolution varies by instrument and product; OLCI ocean-colour products are available at approximately 300 m (full resolution) and 1,200 m (reduced resolution).

This dataset provides global Level-3 mapped chlorophyll-a data derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite. The product provides near-surface chlorophyll-a concentration for ocean colour applications and is available at spatial resolutions of 4 km and 9 km.

Copernicus Sentinel-2 provides multispectral satellite imagery for monitoring land surfaces, vegetation, soil, water cover, inland waterways and coastal areas. The MultiSpectral Instrument (MSI) acquires data in 13 spectral bands at spatial resolutions of 10, 20 and 60 metres. Available products include Level-1C top-of-atmosphere reflectance and Level-2A atmospherically corrected surface reflectance. Data are available free of charge through the Copernicus Data Space Ecosystem.

The NOAA Coral Reef Watch Daily Global 5km Satellite Marine Heatwave Watch provides daily global monitoring of marine heatwaves at 5 km spatial resolution. Marine heatwaves are identified as periods of anomalously high sea surface temperature relative to a long-term daily temperature threshold and are classified according to their intensity. The product is derived from the NOAA Coral Reef Watch CoralTemp satellite sea surface temperature dataset and includes historical and near-real-time marine heatwave information from 1985 to the present.
