Description

This collection contains in situ data from the Tasman Tidal Dissipation Experiment (T-TIDE) that was analyzed in Marques et al. (2024). These observations were taken around a small-scale bump embedded on the continental slope of Tasmania to study the internal tide and near-bottom turbulence over deep-ocean topography (water depth of about 2000 m). The in-situ data comprise two moorings (T1 and T2) and shipboard data (FastCTD and NT1). Additional data and model results (in metadata and extradata folders) that are part of the paper are also included.

Mooring data cover heights between 10 and ~600 m above the bottom and includes velocity and temperature data. Velocity was measured by two downward-looking Acoustic Doppler Current Profilers (ADCPs) in each mooring. The frequencies of the two ADCPs were 300 and 75 kHz, where the former has higher vertical resolution and measured velocity in the bottom ~100 m. Temperature was measured at 2 Hz throughout the mooring with ~35 thermistors, where the spacing was 10 m in the bottom 200 m. The moorings also included either 2 (T2) or 3 (T1) Conductivity-Temperature-Depth (CTD) sensors. Mooring data is provided at multiple levels of data processing (level 1, level 2, and level 3). Level 3 includes turbulence estimates from temperature variance. Code for processing the mooring data and additional higher-level processing for the paper is included in the subfolder dataproc.
