Details of Current Profiler Marsaxlokk Malta


Dataset identification

Title of datasetCurrent Profiler Marsaxlokk Malta
Narrative summary of datasetA Nortek AquaDopp ® 400kHz current profiler deployed within a shallow bay in Malta. The deployment was conducted for the EU Horizon 2020 research project ‘Tools for Assessment and Planning of Aquaculture Sustainability’ (TAPAS) and its aim was to produce scientific research data to support the sustainable expansion of coastal aquaculture systems. The current profiler was deployed for 16 months to help model the hydrodynamic activity, and to complement the on-going integrated multitrophic aquaculture (IMTA) study. The collected data was input into nutrient dispersion modelling software to illustrate the movement of nutrients. The current profiler collected current speed and direction by 1-meter increments from the sensor. The profiler system was re-positioned periodically. All specific data set pertaining to each deployment is in the metadata file.
Summary of processing methodologyData was extracted from the AquaDopp Profiler and the large project file was converted to working data files using AquaPro

Data quality processing informationData quality was processed using Nortek Surge software. Values for roll and pitch were filtered if higher than 10 degrees. Data collected during deployment and retrieval also removed in the filtering process. Water depth of actual data points was calculated with mount offsets, cell sizes and water depth of the deployment area. Data is good quality.
