Description

This collection contains in situ data from the Tasman Tidal Dissipation Experiment (T-TIDE) that was analyzed in Marques et al. (2020). These data were obtained from three moorings (M5, T5 and T6) and one shipboard station (S2) taken between January and March in 2015. Mooring data is presented in two levels: raw (gridded) and processed (with higher-level quantities). Station data is given in one file only.

Time variables include "time" and "yday". The former is in Matlab's datenum format of the UTC time and the latter is the UTC yearday in 2015. "z" refers to depth (of the observations) and "p" is the pressure.

Horizontal velocity is denoted by (u, v), where u (v) is the zonal (meridional) component. The magnetic declination used in the calculation is 15.189 clockwise from the geographic north.

For hydrographic data, a number of different variables are used:
- t: in situ temperature.
- s: practical salinity.
- sgth or sgth0: potential density relative to the surface.
- SA: absolute salinity.
- CT: conservative temperature
- N2: buoyancy frequency squared.

Higher-level variables include (see also Marques et al. (2020)).
- eta: vertical isopycnal displacement.
- HKE: horizontal kinetic energy.
- APE: available potential energy.
- pp: (internal-wave) pressure perturbation.
- up (or vp): zonal (or meridional) velocity times pressure perturbation.
- FU (or FV): zonal (or meridional) energy flux.

Suffixes to variables:
- avg: time(wave)-averaging (see Marques et al. (2020)).
- cumint: cumulative (depth) integral.

Processed dataset include time-filtered data for several different frequencies:
- f0: inertial frequency.
- D2: semidiurnal frequency (bandpassed data).
- D1: diurnal frequency.
- M2: lunar semidiurnal frequency (harmonically fitted data).
- S2: solar semidiurnal frequency.
- M2S2: variables from M2 added to S2.
- O1, K1 and O1K1: similar to M2, S2 and M2S2, but for diurnal tidal frequencies.
