SeaRanger 2024: Monitoring data recorded during RV ALKOR cruise AL607 - Gadus morhua body and gonad measurements

This data contains monitoring data of the RV ALKOR cruise AL607 conducted in February 2024 (February 10th – February 16th) in the Western Baltic Sea by the University of Hamburg. Sampling activities conducted during this teaching cruise was part of the international sampling efforts to investigate the spawning activity of Western Baltic cod (Gadus morhua) coordinated by the Western Baltic cod Forum (WBCF). The data set includes cod single fish analysis data. All single fish measurements were made directly on board. Full wet weights of cod were measured and subsequently cod were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded, and Otoliths were taken.

Winter cod 2024: Monitoring data recorded during RV ALKOR cruise AL606 - Gadus morhua body and gonad measurements

This data contains monitoring data of the RV ALKOR cruise AL606 conducted in January 2024 (January 22nd – January 30th) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year monitoring programme Winter cod 2021-25 (Monitoring winter spawning activity of Western Baltic cod (Gadus morhua) (2021-25)) of the University of Hamburg aiming at investigating the early-winter spawning activity of Western Baltic cod to identify potential climate-induced shifts in spawning phenology. The data set includes cod single fish analysis data. All single fish measurements were made directly on board. Full wet weights of cod were measured and subsequently cod were gutted and liver weights, gonad weights and sexes, gutted wet weights (i.e., gutted wet mass), gonad stages and liver nematode infestations were recorded, and Otoliths were taken.

MGF-Ostsee Project EMB238

Hydro-physical investigations (CTD Data) at cruise EMB238 of IOW as part of the MGF-Ostsee Project: Potential effects of closure for bottom fishing in the marine protected areas (MPAs) of the western Baltic Sea - baseline observations

Modeled 3D biogeochemical processing of phosphorus from the Warnow River in the western Baltic Sea from 1995 to 2014, base scenario, v05 Unterwarnow turnover

A marine physical biogeochemical model simulation was performed with the model MOM-ERGOM for the years 1985 to 2014 covering the Baltic Sea. Previously, MOM-ERGOM had been initialized for several decades. The model output has been validated with measurement data of the "IOW Baltic Monitoring and long-term data program" (https://www.io-warnemuende.de/iowdb.html) and from the HELCOM database (http://ocean.ices.dk/helcom/Helcom.aspx). The years 1995 to 2014 are available here. The model simulation was forced by coastDat2 COSMO-CLM data (doi: 10.1594/WDCC/coastDat-2_COSMO-CLM). Riverine phosphorus input of the Warnow River was calculated with the Soil & Water Assessment Tool (SWAT; Bauwe et al., 2019, doi: 10.1016/j.ecohyd.2019.03.003). Phosphorus from the Warnow River has been tagged in the model simulation according to a method by Menésguen et al. (2006, 10.4319/lo.2006.51.1_part_2.0591). Therefore, all phosphorus-containing model variables exist twice in the output: once as regular variables and once as tagged variable. The default phosphorus input by the Warnow River based on real phosphorus release patterns and real atmospheric conditions was used (PhosWaM SWAT case "ist"). The turnover of phosphorus compounds in the Unterwarnow was calculated based on the “Unterwarnow turnover estimation v04” (see final project report of PhosWaM for details).The work was performed within the project PhosWaM funded by the German Federal Ministry of Education and Research (BMBF, FKZ 033W042, https://www.phoswam.de). PhosWaM is one of 15 joint research projects in the funding measured ReWaM of the funding priority NaWaM in BMBF framework program FONA (details in the project description). The simulation was performed at the North-German Supercomputing Alliance (HLRN). The model output data were processed and evaluated on servers provided by the project 'PROSO - Prozesse von Spurenstoffen in der Ostsee' (FKZ 03F0779A).

Therefore, all phosphorus-containing model variables exist twice in the output: once as regular variables and once as tagged variable. The phosphorus input by the Warnow River based on real phosphorus release patterns and real atmospheric conditions was modified in order to comply with BASP (Baltic Sea Action Plan) targets (PhosWaM SWAT case "15").
