Same stuff on 12100 kHz.

I assume it's CODAR. An over the horizon wave height measureing
(or something like that) HF radar,

Many thanks for clearing this up.

Here's the web site: http://www.codaros.com/

There are currently 72 SeaSondes.

So if each transmitter occupies 100 kHz, that's 7200 kHz of HF
bandwidth consumed by a single company, and there's 4100 kHz more
coming on line for a total of 11.3 mHz! Or have I misplaced a decimal
point someplace?

9 January 2006

California purchases 41 SeaSonde units for new program.

California has started building the infrastructure for the new $21M
Coastal Ocean Currents Monitoring Program (COCMP), designed for aiding
critical operational and research endeavors. A key component of this
program will be the continuous surface current outputs from an
extensive SeaSonde® network. The acquisition of 41 new SeaSonde and
Long-Range SeaSonde units being installed as part of this program will
bring the total number of units operated in the state to 57.

This new network will provide continuous coverage of the ocean surface
currents along the entire 1100 miles of California's coast out to
approximately 120 miles offshore. Highest resolution coverage will be
set at the most critical areas, such as inside of San Francisco Bay.
Once completed, the state will boast having the world's most advanced
ocean current monitoring system.

This project made front page news on 8 January 2006 in Silicon
Valley's largest newspaper, the San Jose Mercury News. To view the

In addition, the COCMP program has a very comprehensive website,
including more technical details on the program, participant
information, downloadable press releases and presentations, as well as
links to other related web sites. A statement of support from Governor
Arnold Schwarzenegger is highlighted on their home page. See
www.cocmp.org.
