This dataset comprises physiological measurements of the southern king crab, Lithodes santolla, exposed to different oxygen conditions. Physiological variables include oxygen consumption, heart rate, and ventilation rate. The dataset was generated to evaluate the physiological responses of L. santolla to environmental variation in temperature and oxygen availability. Physiological data were collected in 2016 at the Alfred Wegener Institute, List/Sylt, Germany, using animals transported from Punta Arenas, Chile, during the PS98 expedition (10 April to 11 May 2016). Oxygen concentration was measured using optical oxygen sensors (PSt3, PreSens GmbH, Germany). Heart and ventilation rates were recorded by infrared photoplethysmography (photoplethysmographs and amplifiers from iSiTEC GmbH, Germany) and digitized using a PowerLab acquisition system (ADInstruments, United Kingdom).
This dataset comprises physiological and metabolic measurements of the southern king crab, Lithodes santolla, exposed to different temperatures (0–25 ºC) and two oxygen conditions (Normoxia: 21 kPa and Reduction: 12 kPa). Physiological variables include oxygen consumption, heart rate, and ventilation rate.

Ce projet a pour but l'etude de l'influence des rejets de chaleur a la surface du sol sur les ecoulements des basses couches de l'atmosphere. Une telle influence peut etre mise en evidence dans le cas de l'ilot de chaleur urbain. Un des objectifs du projet est l'etude des mecanismes de ventilation des villes suisses en toporaphie complexe. Les outils utilises sont des modeles physiques et des modeles numeriques. (FRA)
La recherche a pour but l'etude des perturbations que peuvent creer les rejets de chaleur dans les basses couches de l'atmosphere. Les rejets de chaleur consideres sont lies aux regions industrielles et urbaines ainsi qu'aux grandes installations de production d'energie. Les perturbations apparaissent sous la forme de panaches et de cellules convectives et en particulier sur les cellules carateristiques de l'ilot de chaleur urbain. En effet c'est par la connaissance des mecanismes lies a la formation des cellules et a leur interaction avec les ecoulements regionaux que les problemes de qualite' de l'air en ville pourront etre abordes d'une maniere plus approfondie.
