Description
Larvae of fish from families Engraulidae and Clupeidae were sampled. Sampling was mainly pelagic, thus mainly by Petersen's young fish trawl. Data proceed from the Thor expeditions 1908-1910 but data from other expeditions (Thor 1905 and 1906) and other vessels (Nordboen and Pangan) are incorporated in the report, encompassing years 1904-1911
Data Records
The data in this sampling event 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 341 records.
1 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
Fish larvae of the families Engraulidae and Clupeidae were sampled mainly by trawling with Young fish trawl and Petersen trawl, depending on the expedition. Both methods are most suitable for pelagic fish larvae rather than coastal ones, as reported by Schmidt (1912).
| Study Extent | The dataset proceeds from the report by Fage (1920), merging data from Thor winter and summer expeditions to the Mediterranean and adjacent seas (1908-1910), with data from Thor expeditions to the N-W Atlantic (1905 and 1906). Some data from the Red Sea are also present, although this area was not the target of the expedition. |
|---|---|
| Quality Control | The dataset was digitized manually from scanned documents. Original names regarding taxonomy and sampling location were kept as a reference. At the same time taxon names were cross-checked against the World Register of Marine Species (WoRMS); while the original sampling coordinates were plotted using Google Earth in order to double check that they are located in the sea. All data were checked for inconsistencies, both for the range of values, but also compared to other datasets from the same series, collected at the same station. Any problematic records were recorded in a remarks field in the data. |
Method step description:
- Abundance data related to larvae of Engraulidae and Clupeidae, present in the report by Fage (1920) were digitized. To link these data with the environmental information recorded in correspondence of each sampling and published in Schmidt's report (1912), an unique ID was assigned to each sampling event whenever possible. Consequently each record can be linked to a set of geographical coordinates, a date, temperature and salinity data. We consistently kept the information from Schmidt as main reference, also in case of mismatch, typos or missing information in Fage's report. As abundance data were broken down into different size classes, we kept the information, i.e. for each sampling event there might be different records if different size classes were present.
