Article Synopsis
  • - The study analyzes Early Eocene Arctic climate dynamics using sediments to understand climate patterns without ice, focusing on orbital variability that influenced climate changes during that period.
  • - High-resolution records of lipid biomarkers and pollen indicate that temperature changes were linked to orbital cycles, with significant sea surface temperature increases tied to higher precipitation and nutrient supply in the Arctic Basin.
  • - The research suggests that Arctic climate responses during the Early Eocene were significantly influenced by local insolation, showing stronger temperature variability compared to the deep ocean and tropics, even in the absence of ice-albedo feedbacks.

Estimating the spatial position of marine mammals based on digital camera recordings.

Estimating the spatial position of organisms is essential to quantify interactions between the organism and the characteristics of its surroundings, for example, predator-prey interactions, habitat selection, and social associations. Because marine mammals spend most of their time under water and may appear at the surface only briefly, determining their exact geographic location can be challenging. Here, we developed a photogrammetric method to accurately estimate the spatial position of marine mammals or birds at the sea surface.

Fracture zones in the Mid Atlantic Ridge lead to alterations in prokaryotic and viral parameters in deep-water masses.

We hypothesized that mixing zones of deep-water masses act as ecotones leading to alterations in microbial diversity and activity due to changes in the biogeochemical characteristics of these boundary systems. We determined the changes in prokaryotic and viral abundance and production in the Vema Fracture Zone (VFZ) of the subtropical North Atlantic Ocean, where North Atlantic Deep Water (NADW) and Antarctic Bottom Water (AABW) are funneled through this narrow canyon and therefore, are subjected to intense vertical mixing. Consequently, salinity, potential temperature, oxygen, PO4, SiO4, NO3 were altered in the NADW inside the VFZ as compared to the NADW outside of the VFZ.
