Ocean & Climate Data Sources

1. Copernicus Marine Service (CMEMS)

DiveSight uses multiple Copernicus Marine products for forecasting.

Products used:

• GLOBAL_ANALYSISFORECAST_PHY_001_024 (GLORYS12V1 — ocean physics, depth-resolved temperature, currents, salinity)
• OCEANCOLOUR_GLO_BGC_L3_NRT (chlorophyll-a, 4 km multi-sensor)
• OCEANCOLOUR_GLO_BGC_L3_MY (chlorophyll-a, 300 m OLCI)
• GLOBAL_ANALYSISFORECAST_WAV_001_027 (VHM0 wave height)
• SST_GLO_SST_L4_NRT_OBSERVATIONS_010_001 (OSTIA SST)

License: Free access under the Copernicus Marine Service License. Commercial use permitted. Redistribution permitted with attribution.

Required attribution text (verbatim):

"Generated using E.U. Copernicus Marine Service Information; https://doi.org/[DOI per product]"

Per Copernicus policy, attribution should cite the specific product DOI used. DiveSight should maintain an up-to-date mapping:

2. HYCOM (Hybrid Coordinate Ocean Model)

Used historically for ocean circulation; may be retained as fallback for depth-resolved data.

License: Public domain (U.S. Department of Defense / Navy). No restrictions on use or redistribution.

Recommended attribution:

"Ocean circulation data provided by the HYCOM Consortium, funded by the National Ocean Partnership Program (NOPP). See https://www.hycom.org."

Suggested academic citation (if relevant):

Chassignet, E. P., Hurlburt, H. E., Smedstad, O. M., Halliwell, G. R., Hogan, P. J., Wallcraft, A. J., Baraille, R., & Bleck, R. (2007). "The HYCOM (HYbrid Coordinate Ocean Model) data assimilative system." Journal of Marine Systems, 65(1-4), 60–83. https://doi.org/10.1016/j.jmarsys.2005.09.016

3. NASA GOT4.10c Tide Model

Primary tidal model. GOT4.10c harmonic constants are fit once per dive site; the server synthesizes tide curves on demand via classical harmonic analysis (Σ f·A·cos(ω·Δt + V0 + u − G), with Schureman 1958 nodal corrections) and shifts each curve to an approximate MLLW / chart-datum reference using the 29-day predicted minimum. Covers ~20,000 dive sites as the primary source.

Author: Dr. Richard D. Ray, NASA Goddard Space Flight Center License: Free public-use NASA data. No commercial-use restrictions.

Required attribution:

"Tidal predictions generated using GOT4.10c (Ray 2013), courtesy of Dr. Richard Ray, NASA Goddard Space Flight Center."

Academic citation:

Ray, R. D. (2013). "Precise comparisons of bottom-pressure and altimetric ocean tides." Journal of Geophysical Research: Oceans, 118(9), 4570–4584. https://doi.org/10.1002/jgrc.20336

Note on nearest-neighbor rescue: ~3,100 coastal dive sites whose coordinates fall inside GOT4.10c's 0.5° land mask inherit harmonic constituents from the nearest valid GOT4.10c site within 15 km (median donor distance 6 km). These sites carry a fallback_source: 'nearest-valid-neighbor' stamp in our database for auditability. The underlying attribution is still GOT4.10c — no additional citation required.

3B. EOT20 Tide Model (DGFI-TUM)

Secondary tidal model used for sites in enclosed and semi-enclosed basins (Mediterranean, Black Sea, Baltic, Caspian, and similar) where GOT4.10c's 0.5° grid has no usable solution. EOT20 is a 1/16° global ocean-tide model with substantially better coastal and enclosed-sea fidelity.

Academic citation:

Note: EOT20 amplitudes and phases are bilinearly interpolated at each site's coordinates, then fed through the same harmonic synthesis used for GOT4.10c. Sites sourced from EOT20 carry a fallback_source: 'eot20' stamp in our database.

4. Apple WeatherKit

License: Apple WeatherKit API Terms. Attribution is mandatory and enforceable — Apple requires a specific attribution display.

Required attribution (verbatim, per Apple's Data Source Attribution policy):

On any screen displaying WeatherKit data, show:
