Data Access
There are two
types of data available on this web page: in situ transport
estimates from the calibration cruises, and transport estimates from
the calibrated cable voltages. The in
situ section data represents transports integrated either from
dropsonde or lowered acoustic doppler profiler (LADCP) data. Dropsonde
or LADCP data are collected at nine sites across the Florida Straits at
roughly the same location as the submarine cable. (Note some cruises
during the early 1990s used only eight sites.) Sections have been taken
from the early days of the project in the 1970s until the present, and
in the future up to 12-14 cruises per year will be done along this
line. The transport data from the cruises during 1991 to the present
have all been collected and reprocessed using a consistent methodology;
these data are available as an ASCII
FILE, where the columns are Year, Month, Day, Hour, Transport, and
observation type, while the rows each represent one cruise. The
dropsonde or LADCP data has been corrected for barotropic tide using
the tidal constituents derived by Mayer et al. (1984).
The daily mean transport estimates from the submarine cable voltage and
in situ transport estimates from the calibration
cruises in the last 365 days is shown above in the figure.
Transport data from the submarine cable is also available from this
site. The cable measurements have been corrected for geomagnetic
variations and the tidal signal has been removed. There are several
gaps in the time series due to electronics problems that will hopefully
be solved in the near future.
The daily mean transport estimates from the submarine cable voltage
from year 2000 until the present is
shown below in the figure. Updates to the
time series are provided daily in an
automated manner.
The daily mean transport values are available as ASCII tables
for
each year. Each file has one year of daily transport estimates, the
units are Sverdrups (1 Sv=106 m3s-1).
Missing data, which can occur for a variety of reasons, are denoted by
"NaN".

The historical data, from
1982 until 1998, when the project was led by Dr. Jimmy Larsen is
available here.
How to acknowledge
data from the Florida Current Project:
Data from the
Florida Current cable and sections are made freely available to the
public. The project scientists would appreciate it if you added the
following acknowledgment to any publications that use this data;
"The Florida
Current cable and section data are made freely available on the
Atlantic Oceanographic and Meteorological Laboratory web page (www.aoml.noaa.gov/phod/floridacurrent)
and are funded by the NOAA Office of Climate Observations."
The project
scientists would also appreciate it if you informed us of any
publications or presentations that you prepare using this data.
Continued funding of this project depends on us being able to justify
to NOAA (and hence the US Congress) the usefulness of this data.
