DATASET TITLE
ODER~SO | Oder River Disaster 2022 | Data | SP10b: Benthic Invertebrate data
DESCRIPTION
This dataset contains identification results, abundance and calculated dry weight data for benthic invertebrates sampled from the Oder river via air-lift-sampler in three samplings (April 2024, April 2025 and October 2025)
OBJECTIVE
The dataset quantifies abundance and dry weight of benthic invertebrates across three habitat types along the German stretch of the Oder river, in three sampling campaigns.
GEOGRAPHIC COVERAGE
Sampling sites were distributed along the German stretch of the Oder river (km 559-704)
System: Oder River
Habitats: gryone field (BF), groyne head (BK), stream Center (SS)
TEMPORAL COVERAGE
April 2024 - October 2025
DRY WEIGHT CALCULATION
Dry weight was calculated according to length/mass correlations listed in these publications:

DATA ORGANIZATION
Sheet 1 Identification data
Date: Date of sampling
Site: includes river kilometer (599-704) and habitat (BF-groyne field; BK-groyne head; SS-river center)
Sample Code: includes river kilometer (559-704) and habitat (BF-Buhnenfeld; groyne field; BK-Buhnenkopf; groyne head; SS-Stromstrich; river center) and sampling date (eg. 240422 -> April 22 2024)
ID_AQEM: ID_AQEM code for species, no available ID for Olecryptotendipes macropodus (OM1)
Taxon: name of taxon
Length: Length of individual in mm
additional animals not measured: addition animals of that taxon within the sample that were not measured but counted
Notes: additional notes, fragmentary animals, adult terrestrial insects, empty shells, exuviae etc were not used for further analysis, some animals were sampled for isotope analysis
TaxaGroup: taxonomic information
Family: taxonomic information
Subfamily: taxonomic information
Calculated Dry Mass (mg): Dry mass in mg for that individual, calculated from length or head width, some taxa (see sheet 3) were dried and weighted collectively per sample instead
Sheet 2 Abundance and habitats

Kilometer: River kilometer of sampling site according to ELWIS
Habitat: BF-groyne field; BK-groyne head; SS-river center
Sampling: Sampling season (2404 - April 2024)
Abundance m2: Abundance of taxon and sampling, individuals per square meter
Dry Mass(mg)/m2: Dry mass (mg) by square meter, calculated from mean dry mass and abundance, or weighted in case of oligochaeta and polychaeta
Mean Dry Mass (mg): mean dry mass (mg) of individuals for which length was measured
number of animals measured: Number of individuals for that taxon for which length was measured
Lat: Latitude of sampling site
Long: Longitude of sampling site
Location: closest settlement to sampling site
Date: date of sampling
