Two new HORIZON EUROPE and one Spain funded projects

TRIDENT

TRIDENT-Technology based impact assessment tool for sustainable, transparent deep sea mining exploration and exploitation

TRIDENT is funded under the EU Horizon Europe Research program. TRIDENT aims to contribute to a sustainable exploitation of seabed mineral resources, by developing a reliable, transparent and cost-effective system for prediction and continuous environmental impact monitoring of exploration and exploitation activities in the deep sea. This project is funded with approximately 16 Meuro for 60 month. Starting date: (not fixed yet). Partnership: INESCTEC, Porto-Portugal (coordinator) and 25 other European institutions. CINTAL is involved in machinery noise measurement and analysis. People involved from CINTAL/SiPLAB: S.M.Jesus and others to be contracted. [more...].


red tuna

ACTTHUN-Acoustic and computer vision technique for non-invasive estimation and monitoring of bluefin tuna biomass and its behavior in different acoustic landscapes

ACTTHUN is funded by the Ministerio de Ciencia e Innovacion (Spain). ACCTHUN aims at developing methodologies and techniques for improving the bluefin tuna (BFT) wild stock estimation addressing two main challenges: to obtain a reliable estimation of the number, dimensions and weight of captured individuals and to provide fishery-independent abundance indices for wild BFT. Also, to provide knowledge about the influence of underwater soundscape on BFT, characterizing the pressure and particle motion fields, describing the related BFT behaviour. This project is funded with approximately XX euro for 36 month. Starting date: September 1st, 2022. Partnership: Universidad Politecnica de Valencia (UPV) Spain, (coordinator) and several other institutions. People involved from CINTAL/SiPLAB: S.M.Jesus and others to be contracted. [more...].

Logo of project JONAS

PAM2py

download zip or github, a Python open source version of the PAMGuide package for Passive Acoustic Monitoring that features the Exchange Data Format (EDF) for facilitated underwater acoustic data sharing and metadata handling. Python allows for a crossplatform licence free processing of raw acoustic data and EDF output. A library of Python routines for EDF data reading and writing are also available. See manual here.


Head wave propagation using Traceo

TRACEO

an efficient Gaussian beam 2D ray tracing model for underwater acoustic propagation, handling full bottom and water column range dependency, obstacle scattering and producing particle velocity outputs. See manual here and download a free copy for Fortran. A C version for linux and/or Windows is available here and for GPU here.
