About us
Welcome to the Current Meter Archive!
What we do:We take existing moored current meter data,
process it using a handful
of MatLab routines, and output one tarfile containing all the data in
one standardized format.
We have included here (v. 1) data from OSU
(Buoy Group and Deep Water Archive) as well as 7 different smaller
datasets obtained from Carl Wunsch.
Data format:
All data files are (to the best of our knowledge) in mks units --
velocities in m/s, temperatures in deg. C, salinity in psu, pressure in
db.
The archive is made for
matlab users (please do not contact us with questions about how to use
MatLab). The advantage of using this archive over downloading
the original files from say OSU is that one can easily extract the
records of interest based upon the metadata.
- As a very simple example:
- to find the records that meet the following criteria -
index_useful = find(abs(Lat)>5 &
BeginTime> datenum(1992,10,14)
& Depth < 100 & Duration > 180 & Seafloor_depth > 3000);
& Depth < 100 & Duration > 180 & Seafloor_depth > 3000);
This simple command would find all the
records that are:
a) poleward of 5 degrees, and
b) have a start date after Oct 14,
1992, and
c) are in the upper 100m of the water
column, and
d) are at least 180 days long, and
e) are in water at least 3000m deep.
The user can construct whatever search
they like, limited only by the list of metadata.
To extract the actual data records
found with the above command, one uses commands like:
We are steadily working to
increase our data holdings and encourage
data submission. Please contact
Rob Scott for more information about the archive or for information
on submitting your data set..Data >>
