Denitrification rates in boreo-arctic sponges - data of sponge species from Korsfjord (Norway) and the Schulz Bank (Arctic Ocean) ...
Sponges are commonly known as general nutrient providers for the marine ecosystem, recycling organic matter into various forms of bio-available nutrients such as ammonium and nitrate. In this study we challenge this view. We show that nutrient removal through microbial denitrification is a common fe...
