Intro

Creating this webpage to better describe the various methods for querying Seacoos data and some of the regularly generated data reports which are available. If you would like to request a specific report of data we are collecting, please add a comment to the 'Data Report Requests' section below.

The data archive for all aggregated Seacoos data products starts at around August of 2004 when the decision was made to keep data instead of keeping only data within a 2 week window.

Reports

An hourly ObsKML file of all the latest in-situ observations is provided at http://carocoops.org/obskml/feeds/seacoos_all_latest.zip and a stylized version of this dataset viewable in Google Earth(free viewer client downloadable from http://earth.google.com )is also produced at http://carocoops.org/gearth/latest_placemarks.kmz

An hourly zipped CSV file of all the latest in-situ observations is provided at http://carocoops.org/obskml/feeds/all_latest.csv.zip

The fields listed in this file are as follows:
platform_handle,observation_type.unit_of_measure,time,latitude,longitude,depth,measurement_value,data_url,operator_url,platform_url

An hourly zipped set of shapefiles(same fields as CSV file) of all the latest in-situ observations is provided at http://carocoops.org/obskml/feeds/all_latest_shapefile.zip

Development scripts documenting how the above data feeds are produced are here


Report files and their generation programs can be found at
http://nautilus.baruch.sc.edu/seacoos_data/CSV/

or if using an ftp client ftp://nautilus.baruch.sc.edu

with user/pass = dataftp/data

Reports are provided as csv (comma separated value) files which should open directly in programs like Excel.

A report of the past 3 day wind observations
http://nautilus.baruch.sc.edu/seacoos_data/CSV/seacoos_wind_prod_latest_3days.csv

A report of the past 3 day sst observations
http://nautilus.baruch.sc.edu/seacoos_data/CSV/seacoos_sst_prod_latest_3days.csv

Monthly reports are also created of the wind and sst observations, for example
http://nautilus.baruch.sc.edu/seacoos_data/CSV/seacoos_wind_prod_2004_08_01_to_2004_09_01.csv

Data Report Requests

None reported.

Query

WMS/WFS

The OGC (Open Geospatial Consortium http://www.opengeospatial.org ) has developed 2 data sharing standards of particular interest in that they allow URL requests of maps (WMS Web Mapping Service) and records (WFS Web Feature Service). Charlton has described the implementation of these services for Seacoos products at the following link.

DODS/OPeNDAP

There are DODS/OPeNDAP relational database server for seacoos in situ data(winds, sst, etc) for

the past 2 weeks observations
http://trident.baruch.sc.edu/dods/seacoos

archived observations older than 2 weeks
http://trident.baruch.sc.edu/dods/seacoos_archive

For example, if you click on the 'HTML Data Request' for sst(sea surface temperature) you'll get the following link
http://trident.baruch.sc.edu/dods/seacoos/sst.html

A station id listing can be found at http://nautilus.baruch.sc.edu/seacoos_data/CSV/seacoos_station_id.csv

The DODS/OPeNDAP server may have some bugs or limitations, so please add a comment to the 'Issues' section below to see what can be done to address.

The URL request for a DODS query could also be generated from another application, making for a friendlier or more focused query interface.

Issues/Other Requests

  • Number of maximum rows returned for a query currently set at 3000

  • not able to return carocoops station id's from archives
