Description
The 16S (V3–V4) metabarcoding results presented here are described in detail in our manuscript and originate from the following sampling efforts: 1. Bi-weekly sampling along the Swedish marine monitoring program across twelve locations in Baltic Proper, Kattegat, and Skagerrak. For all the locations, sampling was performed between February 2016 and March 2017. Additionally, one station (Släggö, Skagerrak) was sampled from August 2015.2. Weekly sampling at multiple depths (5, 10, and 15 meters in most cases) at Tångesund, Sweden (Skagerrak), performed in 2016 between August 22nd and October 10th.3. Three longitudinal transects in Skagerrak, performed in 2016 on August 18th, 4. Replicate samples collected at Släggö marine station (Skagerrak) on the same date (August 20th 2019) and stored as filters before DNA extraction for 1 week, 1 month, 3 months, or 6 months, in either -20⁰C or -80⁰C.The extracted DNA was stored at -20⁰C until mid-2023 when the amplicon sequencing was performed. All the contextual data has been obtained from the SharkWeb portal maintained by the Swedish Meteorological and Hydrological Institute.
This dataset was published via the SBDI ASV portal, and has been updated from 'Metadata only' to 'Occurrence' type.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 238,440 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods
Mainly hose sampling from aboard a research cruise vessel. Tangesund samples were collected with a bottle, thus they come from a particular depth and not a range of depths.
