The MoHaBa project (Modellierung ganzjähriger Habitatpräferenzen von Blau-, Finn-, Zwerg- und Buckelwalen im zirkumpolaren Südozean, BMEL-Projekt; 2018-2022) was a project financially supported by the German Federal Ministry of Food and Agriculture (BMEL) through the Federal Office for Agriculture and Food (BLE). The main objective of the MoHaBa project was to provide detailed, quantitative knowledge about the spatial and temporal distribution of baleen whales in the Southern Ocean. The project focuses on modelling the dynamic habitat suitability of four baleen whale species in the Southern Ocean using visual sightings and passive acoustics data: Antarctic Minke Whales (Balaenoptera bonaerensis); Antarctic Blue Whales (B. musculus intermedia); Fin Whales (B. physalus); Humpback Whales (Megaptera novaeangliae)] The main results of the project are presented in the following papers: El-Gabbas A, Thomisch K, Van Opzeeland I, Burkhardt E, Boebel O (2023) Dynamic species distribution models of Antarctic blue whales in the Weddell Sea using visual sighting and passive acoustic monitoring data.

Abstract Aim Species distribution models (SDMs) are essential tools in ecology and conservation. However, the scarcity of visual sightings of marine mammals in remote polar areas hinders the effective application of SDMs there.
