Eavesdropping at the speed of light: distributed acoustic sensing of baleen whales in the Arctic

Léa Bouffaut, Kittinat Taweesintananon, Hannah Joy Kriesell, et al.

Subjects: Marine Biology, Physical Sciences and Mathematics, Signal Processing

In a post-industrial whaling world, flagship and charismatic baleen whale species are indicators of the health of our oceans. However, traditional monitoring methods provide spatially and temporally undersampled data to evaluate and mitigate the impacts of increasing climatic and anthropogenic pressures for conservation. Here we present the first case of wildlife monitoring using distributed [...]

Differences in running velocity and boldness between male and female Atlantic sand fiddler crab (Leptuca pugilator)

Atlantic sand fiddler crabs (Leptuca pugilator) exhibit an extreme case of sexual dimorphism with the male crabs wielding an enlarged dominate claw that can account up to 40% of an individual’s total body mass. The salt pans found in marine marshes are commonly colonized by fiddler crabs and have limited coverage from avian predators, making the ability to quickly run back their burrows, an [...]

Tidal marsh resilience to sea level rise controlled by vertical accretion and landward migration under nature-based human adaptation scenarios

Tidal marshes are not only lost to human disturbance but also face the threat of sea level rise (SLR). However, current earth system models used to estimate future changes in wetland extent omit wetland’s real responses to SLR without field observations. We synthesised global data on sediment accretion rate (SAR) and surface elevation change (SEC) for tidal marshes and developed a mathematical [...]

The Baltic TRANSCOAST approach – investigating shallow coasts as terrestrial-marine interface of water and matter fluxes

Manon Janssen, Michael E Böttcher, Martin Brede, et al.

In Baltic TRANSCOAST we study the physical, biogeochemical, and biological processes at the land-ocean interface. The coastal zone is heavily impacted by various human activities as well as by geomorphological and climatic processes – on both the land and the sea side. Land-sea interactions at low lying coastal areas that are often dominated by peatlands, and are a common feature along the Baltic [...]

The aim of this work is to identify main impact factors affecting variations in the geomorphology of the Mariana Trench which is the deepest place of the Earth, located in the west Pacific Ocean: steepness angle and structure of the sediment compression. The Mariana Trench presents a complex ecosystem with highly interconnected factors: geology (sediment thickness and tectonics including four [...]
