Data from: Rehabilitating the cyanobacteria – niche partitioning, resource use efficiency, and phytoplankton community structure during diazotrophic cyanobacterial blooms

1. Blooms of nitrogen-fixing cyanobacteria are recurrent phenomena in marine and freshwater habitats, and their supplying role in aquatic biogeochemical cycles is generally considered vital. The objective of this study is to analyze if an increasing proportion of nitrogen-fixing cyanobacteria affects (i) the composition of the non-diazotrophic component of ambient phytoplankton communities, and (ii) resource use efficiency (RUE; ratio of chl a to total nutrients) – an important ecosystem function.
We hypothesize that diazotrophs increase community P use, and decrease N use efficiencies, as new N is brought into the system, relaxing N, and concomitantly aggravating P limitation. We test this by analyzing an extensive dataset from the Baltic Sea (> 3700 quantitative phytoplankton samples), known to harbor conspicuous and recurrent blooms of Nodularia spumigena and Aphanizomenon sp. 2. System-level phosphorus use efficiency (RUEP) was positively related with high proportion of diazotrophic cyanobacteria, suggesting aggravation of phosphorus limitation. However, concomitant decrease of nitrogen use efficiency (RUEN) was not observed. Nodularia spumigena, a dominant diazotroph and a notorious toxin producer, had a significantly stronger relationship with RUEP, compared to the competing non-toxic Aphanizomenon sp., confirming niche differentiation in P acquisition strategies between the major bloom-forming cyanobacterial species in the Baltic Sea. Nodularia occurrences were associated with stronger temperature stratification in more offshore environments, indicating higher reliance on in situ P regeneration. 3. By using constrained and unconstrained ordination, permutational multivariate analysis of variance, and local similarity analysis, we show that diazotrophic cyanobacteria explained no more than a few percent of the ambient phytoplankton community variation. The analyses furthermore yielded rather evenly distributed negative and positive effects on individual co-occurring phytoplankton taxa, with no obvious phylogenetic or functional trait-based patterns. 4. Synthesis. Our study reveals that despite the widely acknowledged noxious impacts of cyanobacterial blooms, the overall effect on phytoplankton community structure is minor. There are no predominantly positive or negative associations with ambient phytoplankton species. Species-specific niche differences in cyanobacterial resource acquisition affect important ecosystem functions, like biomass production per unit limiting resource.

ICES Baltic International Trawl Survey for commercial fish species

Baltic International Bottom Trawl Survey dataset includes age- and length-based catch per unit effort data for commercial fish species in ICES Baltic sub-divisions.
The Baltic International Bottom Trawl Survey Database (BITS) includes research vessel data from national fishery laboratories around the Baltic Sea from 1991 until present. Two species are considered as target species; cod and flounder. Herring, sprat and the by catch species (see the BITS manual) have been reported in the years 1991 to 1998. However, it has been optional to report these species since 1999 and the database is therefore not complete with regard to these species. 

Data are given haul-by-haul as mean catch per unit of effort (CPUE) per length class (1 cm interval for all species except herring and sprat, which are reported in ½ cm interval). In addition, mean CPUE and mean weight per length, age, maturity and sex are given haul-by-haul for sub-samples of the target species.

TROPHOS/PODO-I work-database I (23/01/2004): Meiobenthos from station 330 - structural and funtional biodiversity on the Belgian Continental Shelf

The principle aim of this research was to investigate the morphometry of nematode communities as triggered by a phytoplankton spring bloom deposition in a well oxygenated North Sea sampling station. Length and width measurements are available together with densities.
The response of nematode communities to the sedimentation of a spring phytoplankton bloom in a sandy, well-oxygenated sediment in the Southern North Sea is investigated from early March to July 1999) with monthly intervals. Both structural (nematode density, diversity, vertical distribution and community composition) and functional (feeding type distributions, number of species within feeding groups) characteristics were investigated. Vertical profiles of pigment concentrations in the water column were determined.
SHARK - National marine bacterioplankton monitoring in Sweden since 1989

Bacterial cell carbon content, cell volume and concentration at various sampling stations in the Swedish part of the Baltic Sea. Sampling is performed with a rosette sampler or Niskin bottles attached to a wire. Bacterioplankton has been monitored in Sweden since 1989. The national monitoring program was initiated by the Swedish Environmental Protection Agency and is now financed by the Swedish Agency for Marine and Water Management.Monitoring is performed by Umeå University. Data are stored in the Swedish Ocean Archive (SHARK) by the Swedish Meteorological and Hydrological Institute (SMHI).
Bacterioplankton growth rate is an indicator of nutrient status in aquatic environments. Growth rate is an estimate of the consumption of organic carbon in the ecosystem and therefore closely related to the in situ biochemical oxygen demand (cf. BOD7). The growth rate thereby indicates the rate of oxygen consumption that may lead to oxygen deficiency in the water column when exceeding the oxygen supply. Data should be sampled and analyzed according to the HELCOM COMBINE Manual - Part C Annex C11 Guidelines concerning bacterioplankton growth determination (https://helcom.fi/media/documents/Manual-for-Marine-Monitoring-in-the-COMBINE-Programme-of-HELCOM_PartC_AnnexC11.pdf). However, deviations from the manual might occur. Information about the program and the methods are available in Swedish at the website of Swedish Agency for Marine and Water Management, https://www.havochvatten.se/hav/vagledning--lagar/vagledningar/ovriga-vagledningar/undersokningstyper-for-miljoovervakning/undersokningstyper/bakteriell-syrekonsumtion.html. It is recommended to take at least 2 samples at different representative depths of the monitored layers of the water column. Surface layer and deepest layer are prioritised. A sampling frequency of 10 samples per year is preferred for confident annual estimates. Samples should be distributed in the seasonal curve to provide a good coverage of different levels.
