TCHAINS  - Thermistor Mooring data files
-------

all_Tchain_10min.mat  - 10 min averaged data from all ISDE Thermistor Moorings
all_Tchain_60min.mat  - 60 min averaged data from all ISDE Thermistor Moorings

Temperature (degC) and pressure (dbar) are provided as available from each mooring. Salinity is excluded since it was only available for 5 of 93 moorings.

Measured depths are provided where available, otherwise depths are estimated from deployment plan/name (e.g. ##-50 = 50m).

ADCPS -  Current Meter data files
-----


all_adcp_10min.mat  - 10 min averaged data from all ISDE ADCP Current Meters
all_adcp_60min.mat  - 60 min averaged data from all ISDE ADCP Current Meters


Velocity (m/s) is given as u = positive towards EAST, v = positive towards TRUE NORTH.

Measured depths (m) are provided where available, otherwise depths are estimated from deployment (e.g. ##-50 = 50m).

TIME
----

1-2s data files are averaged down to 1 minute.
20/30/60 second data are processed as follows:
- Lowpass filter using PL64 filter (see below) with 20- or 120-minute cutoff
- Subsample data at 10- or 60-minute time steps.
All times are in UTC.

---------
FILTERING
---------

In addition to unfiltered, the data are de-meaned and filtered into four frequency bands using the PL64 filter described in Rosenfeld, 1983 WHOI technical report 85-35, pg.21.

The filtering breakdown is defined as follows:

T = T_mean(z) + T_ST(z,t) + T_DU(z,t) + T_SD(z,t) + T_HF(z,t)
u = u_mean(z) + u_ST(z,t) + u_DU(z,t) + u_SD(z,t) + u_HF(z,t)
v = v_mean(z) + v_ST(z,t) + v_DU(z,t) + v_SD(z,t) + v_HF(z,t)

where:

      Subtidal (ST) = T > 33 hr
       Diurnal (DU) = 16 hr < T < 33 hr
  Semi-diurnal (SD) = 10 hr < T < 16 hr
High-Frequency (HF) = T < 10 hr
