This data set includes single fish cod data collected during the RV ALKOR cruise AL588 conducted in March 2023 (1st to 10th of March) in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year MARSYS teaching cruise program of the University of Hamburg GFP20-1_047. 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.
Real time control will get more important to reduce CSO emissions. Most of the already existing real time control strategies minimize spill flows from the viewpoint of volume minimization. For receiving water the reduction of emissions is much more important. Measured waste water data and probabilistic approach of these data are the focal points in this research. With an UV-VIS spectrometer installed in a swimming pontoon absorption is measured directly and constant. Based on absorption measurements waste water time series curves of COD, TSS and nitrate are shown. A forecast of CSO emissions and the adjustment of ANN for the control system will be the next step included for this project. By statistical evaluation of rain and measured waste water data as well as forecast of CSO emissions with ANN, spill loads can be reduced. The results of this research are basis for future real time control of CSOs in Graz (Austria).
This data set includes single fish cod data collected during the RV ALKOR cruise AL608 conducted in March 2024 in the Western Baltic Sea by the University of Hamburg. The cruise was part of the 5-year MARSYS teaching cruise program of the University of Hamburg GFP20-1_047. 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.
