Abstract. Benthic fluxes of phosphorus (P) were measured in situ the Eastern Gotland Basin (EGB), central Baltic Sea, using benthic landers. A total 40 flux measurements dissolved inorganic P (DIP) on 13 stations at water depths ranging 30–210 m and under different oxygen regimes carried out three cruises during consecutive years (2008–2010) August–September. Our study is first to report DIP proper, it provides most comprehensive dataset organic (DOP) proper existing date. increased with...
In situ incubations of sediment with overlying water provide valuable and consistent information about benthic fluxes processes at the sediment-water interface. this paper, we describe our experiences a variety applications from last 14 years 308 deployments Gothenburg chamber lander systems. We give examples how use sensor measurements for leakage control, in volume determination, control syringe sampling times, resuspension stirring quality. present incubation data oxygen, dissolved...

Abstract. Sedimentary recycling of phosphorus is a key aspect coastal eutrophication. Here, we present data on benthic fluxes dissolved inorganic (DIP) from the Baltic Sea, an area with long eutrophication history. The presented dataset contains 499 individual measured in situ three types chamber landers at 59 stations over 20 years, and cover most Sea sub-basins (Hylén et al., 2025; https://doi.org/10.5281/zenodo.14812160). further information about bottom-water oxygen (O2) concentrations,...
Abstract. Over the last decades, impact of human activities on global nitrogen (N) cycle has drastically increased. Consequently, benthic N cycling mainly been studied in anthropogenically impacted estuaries and coasts, while oligotrophic systems its understanding is still scarce. Here we report solute fluxes rates denitrification, anammox, dissimilatory nitrate reduction to ammonium (DNRA) by situ incubations with chamber landers during two cruises Gulf Bothnia (GOB), a cold, basin located...
Continental margin sediments receive most of the particulate organic carbon (POC) deposited on global seafloor, making them crucial locations in cycle. However, complex environments coastal oceans make it challenging to predict fate sedimentary (OC) these areas. Here we use data from 21 sites Baltic Sea, representing different biological and physiochemical regimes, explore controls OC cycling. To this end, combine situ measured benthic fluxes dissolved inorganic (DIC; proxy for oxidation)...

Benthic nutrient dynamics in the coastal basin Kanholmsfjärden, NW Baltic proper, were studied by situ flux measurements and sediment samplings 2010–2013. The benthic release of NH4 DIP from anoxic sediments Kanholmsfjärden calculated to renew standing stock inventories DIN overlying water roughly 1 year. Starting summer 2012, mixing oxygen-rich into deep part temporarily improved oxygen conditions water. During year oxygenated period, total phosphorus inventory surficial increased 0.4 g P...
Abstract Coastal and shelf sediments affected by transient or long-term bottom water anoxia sulfidic conditions undergo drastic changes in macrofauna communities abundances. This study investigates how early colonization two macrofaunal functional traits (epifauna vs. infauna) affects oxygen, sulfide, pH dynamics anoxic sediment upon recent oxygenation. Large mesocosms (area 900 cm 2 ) with 150-m-deep Baltic Sea soft were exposed to three treatments: (1) no animals; (2) addition of 170...
Abstract. Given the increasing impacts of human activities on global nitrogen (N) cycle, investigations N transformation processes in marine environment have drastically increased last years. Benthic cycling has mainly been studied anthropogenically impacted estuaries and coasts, while its understanding oligotrophic systems is still scarce.
