Oceanography and GIS
Aspiring oceanographers with a geographic foundation can leverage Geographic Information Systems (GIS) for impactful research. This post addresses a Geography undergraduate seeking to specialize in marine science and apply QGIS skills to oceanographic applications. Resources for self-directed learning in this intersection are vital for bridging the gap between geographic expertise and oceanographic specialization. For those seeking broader career guidance, see our related article, "Looking for useful courses or certificates," which explores pathways into ocean-related fields.
How Geospatial Technologies are Helping to Complete the Effort to Map the World's Ocean Floor - Geography Realm
Mapping the world’s ocean floor—a monumental task historically hindered by technological limitations—is rapidly advancing thanks to geospatial technologies. Initiatives like the Seabed 2030 project are leveraging bathymetric lidar, sonar, and satellite altimetry to achieve a complete map by 2030, providing critical data for ocean management and climate modeling. This integrated data ecosystem reveals previously unknown features and supports informed decision-making.

Coastal erosion dynamics along the central coastline of Ghana (2000–2024): a DSAS-based assessment of ecosystem service implications and coastal management
Coastal erosion poses a significant threat to ecosystem services and livelihoods along Ghana’s central coastline. A recent study utilizing the Digital Shoreline Analysis System (DSAS) and Landsat imagery (2000–2024) quantified shoreline change, revealing persistent retreat with mean erosion rates exceeding −1.80 m/year. Spatial variability was substantial, with hotspots identified near Anomabo, Apam, and Winneba. These findings underscore the need for targeted coastal management interventions, including ecosystem restoration and sediment management.
Introducing Global Fishing Watch Layers in ArcGIS Online and the Living Atlas - Esri
Leveraging the power of geospatial analysis, World Data Ocean now integrates Global Fishing Watch layers directly into Esri’s ArcGIS Online and Living Atlas. This collaboration provides researchers, policymakers, and ocean stewards with validated, real-time data on global fishing activity, fostering informed decision-making for sustainable fisheries management. Users can now visualize fishing vessel movements, analyze patterns, and assess the impact on marine ecosystems with unprecedented clarity.

Abundance and physical controls of Mediterranean micro-estuaries
Estuaries, critical transitional zones between freshwater and marine environments, are frequently studied as larger systems, leaving smaller micro-estuaries comparatively understudied. This research defines and investigates the abundance of Mediterranean micro-estuaries—vital coastal features facing increasing anthropogenic and climate-driven pressures. Utilizing a decade of hydrographic data and GIS analysis across seven East Mediterranean sites, we identified 243 micro-estuary-like systems, many previously undocumented.
