28 June 2008

We have just added 74 records from the North Pole Environmetal Observatory of the University of Washington. These include records from Aanderaa current meters, Seabird TPC recorders, and RDI ADCPs. They are from moorings placed very close to the north pole during 3 succesive years (2001-02, 2002-03, and 2003-04). You can access these data here.

7 May 2008

The database now contains 22 current meter and SBE records from moorings deployed along the Lomonosov Ridge as part of the High Latitude Dynamics project. You can reach them here. This is our second data set from High Latitude Dynamics; the other consists of records from the Beaufort Sea.

23 April 2008

We have just added to the database 48 current meter records made along the Equator between longitude 76 East and 93 East. These records were made by the mooring team of the Indian National Institute of Oceanography, as part of Ocean Observing System (OOS) program of the Indian Department of Ocean Development. You can reach the data here or by doing a search on EQCM (the experiment name) or V.S.N.Murty (the name of the PI).

4 March 2008

For some time the database has contained a number of current meter records from PMEL's VENTS experiment. This portion of the VENTS program took place in the northeast Pacific near several undersea volcanic vents, and was an attempt to map the outflow plumes of the vents. Today we have added 57 VENTS current meter records to the existing collection in our database. The new records are from 1994, 1995, 1996, 1997, and 1998. You can access them here.

9 February 2008

We have added 18 current meter records to the DOMES collection. DOMES stands for "Deep Ocean Mining and Environmental Study" and was conducted by NOAA during 1975 - 1977 to determine possible effects of mining manganese nodules on the seafloor. Most of the 18 records are only 2 months in length but complement the 4 longer records that our archive has contained for some years. You can reach DOMES here. Also, we have fixed some depth errors in the 4 previous records.

2 February 2008

The database now contains 33 current meter and TSR records from the Beaufort Sea. They were made during a phase of the High Latitude Dynamics experiment, and are our first dataset from the Arctic Ocean. You can reach them here or here.

13 January 2008

Two more components of ACE 83 have been added to the database, CSIRO's Cape Howe and Newcastle sections - 23 Aanderaa current meter records in all. To reach them, use the links in the 31 December entry immediately below. We are aware of two additional short sections that were part of ACE 83, but since they occurred entirely in relatively shallow water over the continental shelf we have not included them here.

Most of the unfiltered ACE 83 current meter records, as we received them from CSIRO, contained time series described as pressure. Unfortunately we were unable to determine the units of the pressure measurements and have not included them here.

31 December 2007

Fifteen Aanderaa current meter records have just been added to our ACE 83 collection. ACE stands for Australian Coastal Experiment; it took place in 1983-84 off Australia's east coast. The new records are from CSIRO's Stanwell Park component of the experiment (and are new only in the sense that they are new to the Buoy Group database.) You can access them here or by searching on the experiment name "Australian Coastal Experiment". Most of the records are about 6 months in length.

28 November 2007

Eight Aanderaa current meter records taken by CSIRO over the Lord Howe Rise during 1989 - 1990 are available. The records are seven+ months in length and are from two moorings. You can reach them here or by doing a search on the experiment name "Lord Howe Rise 89". Lord Howe Rise is situated in the Tasman Sea between Australia and New Zealand.

17 September 2007

The last moorings of the AnSlope (Antarctic Slope) experiment have been out of the water for more than two years, and we are now able to include here all of the mooring data - including the current meter and Seacat time series. You can access these data here or by doing a search on the experiment name Anslope.

12 September 2007

We have added 12 year-long current meter records from Makassar Strait to the database. These records were obtained by CSIRO during 1993 - 1994. You may be interested in comparing them with curent records taken somewhat farther south in the Strait during the Arlindo experiment. Click here to access the CSIRO data and here to access the Arlindo data.

2 September 2007

The database now contains 4 current meter records from Deep Water Dump Site 106. This location, on the Continetal Slope 106 miles SE of New York City, was used for dumping of sewage sludge from 1986 through 1992. Two current meter moorings were installed by the USGS in order to understand the transport and effects of sludge at the site. Go here to access the data.

25 August 2007

We have just added 26 year-long records from the Labrador Sea to the database. Most of the 26 are from SBE Seacats and two types of current meter. We have included them here under the rubric "Labrador Deep Convection". They were extracted from a group of CDF files provided by Friedrich Schott of IFM Kiel. (These files also contained data from doppler profilers. The doppler records lacked information on bin depths, so we were not able to include them here.) You can access the 26 records that we did include here or by doing a search on the experiment name "Labrador Deep Convection".

29 July 2007

The pressure records from Tom Whitworth's Antarctic Circumpolar Current Choke Point Pressure Monitoring program are now available here to a precision of 0.001 decibar. Initially we had provided only 0.1 db precison, which is not fine enough for many purposes. (Thanks to Richard Ray for pointing this out.) The original pressure records, as uploaded from the Seacat CTDs had a precision of 0.001 db, and the records on this website now have the full precision.

10 December 2006

Not only is it the 71st birthday of the webmaster, who still breathes, but he has added a number of current records from the Gulf of Alaska to the database. The records are from several experiments but are subsumed under PMEL's rubric FOCI, which stands for Fisheries-Oceanography Cordinated Investigations. You can reach this latest addition here or by doing a search on the experiment name FOCI.

28 October 2006

We have added 9 Aanderaa current records from three moorings off the northeast coast of Greenland. We are unsure of the experiment name, so have placed them in the Miscellaneous Atlantic category. You can identify them there by their position (approximately 72 degrees North, 8 degrees West) and dates (June 1987 to June 1988). The mooring names are GS-1, GS-2, and GS-3.

13 October 2006

93 current meter records from the SEQUAL experiment have been added to the database. You can access them here. SEQUAL (which stands for "Seasonal Response of the Equatorial Atlantic") was a joint effort of WHOI and IFREMER during 1983 - 1985. These data are of exceptionally good quality.

The database now contains more than 5000 records from deep sea moorings. Most were made by current meters but the archive also includes time series from temperature recorders, Seacat TPC recorders, pressure recorders, etc.

21 September 2006

Throughout its history the OSU Buoy Group implemented a policy of publishing a data report after each experiment, as soon as the data had been processed. During the Buoy Group's final years these data reports, which contained mooring descriptions, data statistics and plots, were published electronically on the Group's website. That portion of the website has now been fully implemented here. It includes seven data reports, including the Buoy Group's most recent (and final) experiment, AnSlope. Since the data reports contain more information about each experiment than can be found elsewhere in this archive, you may wish to look there first. All of the data reports contain downloadable copies of the data files (the time series).

9 September 2006

We have just placed here some of the mooring data from AnSlope. AnSlope (Antarctic Slope) was a 2-year experiment beginning in 2003. Its goal was to examine and quantify water that sinks at high southern latitudes and flows down the Antarctic slope to contribute to northward-moving deep water masses. Numerous moorings contained current meters and SBE Seacats. Year-long moorings were set in March 2003 and again in March 2004. We have included here brief descriptions of the moored instruments including statistics from the time series. The time series themselves have not yet been released to the public domain and probably will not be available for another year.

UPDATE 17 September 2007: The time series (current meter records, SBE Seacat records, etc.) are now available on this website for download.

31 August 2006

12 new current meter records from the Vents experiment have been added to the database. Vents is a multidisciplinary examination of the region surrounding a number of hot seafloor vents in the Northeast Pacific. The new files were recorded in 1999, 2000, and 2001.

24 April 2006

We have just added new data from the Abrupt Topography experiment to the website. These data are from the ADCP that was deployed at Mooring R2 on the flank of Fieberling Guyot. This instrument recorded velocities from 47 bins, each of which was 4 meters in vertical extent. The top two bins were of poor quality and have not been included here.

At this point the database contains records from Mooring C which was at the top of the seamount, from B2 and B3 which were in deep water northwest of the seamount, and from R2. We do NOT have any data from at least 5 other moorings known to have been deployed - F2, F3, F4, F5 and R3. If you have these data or know where they can be obtained please contact webmaster[at]cmrecords[dot]net so that they can be added to this database. (Please note that our email address has been obfuscated to foil spammers.)

The deep water archive was maintained for several years by the OSU Buoy Group. However,the Buoy Group has disbanded and no longer exists. Several of its members have retired and others have moved on.

We believe that by making available a large world-wide collection current meter records from deep-water moorings we have provided a useful service to the research and educational community. We are aware of no other large, historical, searchable, high quality collection of downloadable current records on the web. We would like to continue making these data available.

To this end, when it became clear that we would not be able to maintain the database indefinitely at Oregon State University, we made arrangements to mirror this collection at the present site, which we expect to remain on the web for the long term. Thus although the Deep Water Archive can still be found at kepler.coas.oregonstate.edu that node is likely to disappear within a year or so. The archive's long term address is now

which has two aliases: www.currentrecords.net and www.current-meter-records.net

We intend to continue adding new current records as we acquire them. If you have any current meter records (including ADCP records) that are from deep water (i.e., beyond the continental shelves) and 6 months or more in length that you would like to include, please contact us.
