Oceanographic data on the Web

Bathymetry Extractor

An online interactive form that allows you to extract isobath segments bounded by specified latitude/longitude ranges. Both the bathymetry and the coastal outlines are extracted. This uses two GEBCO data sets: (1) the worldwide coverage data from 72 deg. S to 72 deg. N; and (2) the polar regions data set above and below 66 deg. latitude. This creates a GIF plot, a PostScript plot, and an ASCII format data set.

NGDC Bathymetry, Topography, and Global Relief

The largest collection of such data available on the Web.

Interactive ETOPO5 Database

Interactive extraction of selected portions of the ETOPO5 global five-minute land elevation and ocean bathymetry data set.

Ocean Color

A site about using data collected in the visible light bands by satellites and aircraft to measure ocean primary productivity and physical oceanographic features.

NOAA Marine Environmental Database

This is a database that holds wind, wave and other marine data collected by the NOAA National Data Buoy Center. An interactive map along with related documentation provide users with detailed information about the positions, period of record and other characteristics of the data here.

GTSPP Database

The Global Temperature-Salinity Pilot Project database is the archival portion of a project to develop and maintain global ocean T-S data that are both up-to-date and of the highest quality. A GTSPP descriptive article can be read for further details.

COADS Project

The Comprehensive Ocean-Atmosphere Data Set (COADS) Project makes available global surface marine data for 1854-1993. These data have been assembled, quality controlled, and made widely available to the research community.

TOGA-COARE Data

Surface, upper-air and ocean observations from the TOGA-COARE experiment (Nov. 92-Feb. 93), which range from 30 S to 30 N and 90 E to 160 W, are available.

ETOPO5 Topography/Bathymetry Data

The Seafloor Sciences Branch at the Naval Research Laboratory at the Stennis Space Center has a Web pages that allows you to extract point or grid data from the 5-minute gridded ETOPO5 database.

The Data Zoo

A large collection of data sets collected during various studies off the California coast. This includes everything from bathymetry datasets to data on currents, weather, surface waves, hydrography, and just about everything else one might measure in such studies.

dynamic ocean topography database

This database at the University of Texas contains gridded monthly average dynamic topography heights as measured by TOPEX/POSEIDON altimetry, and also the corresponding sea level anomalies. PostScript maps are available as well as the processed data.

Live Access to Climate Data

This system, part of the PMEL/TMAP (Thermal Modeling and Analysis Project) lets you browse and extract from a large library of gridded climate data. The data can be interactively plotted or saved as a raw data file in various formats, and both can be downloaded. This library includes the COADS (Comprehensive Ocean and Atmosphere Data Set), the Levitus Annual Climatology, and the Heat Budget of Global Oceans sets. This is an exemplary use of the WWW as an interactive scientific and educational tool.

Modern Average Global SST

This is an online CD/ROM containing SST data derived from the NOAA AVHRR MCSST data set. The data can be interactively extracted as well as the accompanying documentation and analysis programs.

NCAR online data catalog

This is a hypertext catalog of the datasets the folks at NCAR have made available via anonymous ftp. It is a subset of the just really monstrous amount of data they have on the Mass Storage System (MSS), information about which can also be found at this site.

ORI ocean images

An atlas of gif format ocean images derived from the Levitus and other data sets and available for viewing or downloading from the Ocean Research Institute at the University of Tokyo.

Nemo

This is the name given to the collection of data sets electronically archived at the Scripps Institution of Oceanography. It contains searchable CalCOFI and NODC Station Data hydrographic data sets, searchable high resolution CTD data sets, public domain WOCE hydrographic data, the ETOPO5 topographic dataset (along with the capability of extracting subsets thereof), the 1982 Levitus climatology data set (also with the capability of extracting subsets), the Hellerman and Rosenstein wind data, and temperatures and salinities from west coast shore stations. Some of the datasets are extractable via the Web interface and some have to be accessed via a telnet connection.
