"The earliest in situ profile measurements in World Ocean Database 2023 are of temperature at the sea surface (SST) and at about 183 m depth collected on December 15, 1772 (~ 55°S, 22°E) by crew of the paddle boat launched from the Great Britain HMS Resolution, commanded by Captain James Cook. While SST was probably obtained using a water bucket and hand-held thermometers, subsurface temperature measurements were likely collected using a Stephen Hales water sampling bottle with an enclosed thermometer.

How the times have changed!
"The World Ocean Database 2023 (WOD23) is the world’s most complete and representative digital collection to date of near real time and delayed mode oceanographic in situ profile measurements collected from ocean observing systems over the 1772 to 2022 instrumental record. It is a collection of irreplaceable data records containing ~18.6 million water column profiles with ~3.6 billion measurements of 27 commonly measured physical and chemical variables, including 17 essential ocean and 11 climate variables, ~22.7 million meteorological and sea state observations, and more than 245 thousand plankton tows. WOD23 serves as a foundational and reliable data resource by and for global marine communities by making globally scattered and heterogeneous data FAIR, uniformly formatted, quality controlled, and searchable by means of extensive granular metadata. The data were sourced from long-term archived primary data, thus preserving its provenance, traceability, and authoritativeness. New and updated data are made available as quarterly updates to WOD23. The data are used in research applications, including earth system models, climate data reanalysis, and diagnostic studies. WOD23 is an activity of the International Oceanographic Data and Information Exchange, World Data System, and Center for Marine Meteorology and Ocean Climate Data." - WOD23
Our planet, with its mighty environment manager the ocean, is adjusting in the face of human advancement and the collection and archiving of data has never been more important. The WOD23 is a weighty resource that archives data recording how well our planet, in real time and through the lens of ocean and coastal monitoring systems, is adapting to our influence over the last 250 years.
While the WOD23 is not coral‑specific, it outlines capabilities that directly support coral‑reef management, resilience planning, and restoration across the Western Atlantic and Caribbean. The WOD underpins nearly all modern environmental assessments relevant to coral reefs in the Western Atlantic and Caribbean. Its long‑term baselines and standardized datasets are essential for detecting warming trends, assessing bleaching risk, validating satellite products, and understanding the environmental drivers that shape reef health across Florida, the Bahamas, the Antilles, the Mesoamerican Barrier Reef, and the Gulf of Mexico.
The key value of this resource is strategic. WOD data directly support evidence‑based decision‑making for coral‑reef management, restoration planning, and climate‑resilience initiatives. The database enables regional comparisons, informs restoration site selection, and strengthens forecasting models used to anticipate bleaching and other climate‑driven stressors. As the region experiences increased disturbance frequency, declining reef ecosystem functionality the WOD provides the environmental context needed to prioritize investments, coordinate across jurisdictions, and plan for long‑term reef and coastal resilience.
