Description
The “Épocas de Postura da Sardinha” project aimed to obtain information on seasonal planktonic community abundance and diversity, contributing to the biological oceanography characterisation of the sardine reproduction season in Portugal.
The data presented refer to monthly sampling carried out between October 1986 to December 1987 in four transects off Portuguese shelf with RV "Noruega". The zooplankton sampling was carried out using a Bongo net - of 60 cm in diameter and 335 and 500 μm in mesh opening - in double oblique trawls, from around 5 meters up the bottom to the surface. The volume of filtered water was determined using a previously calibrated flowmeter.
This report is a repository of the identification and enumeration data of zooplankton samples. It is intended to contribute to the establishment of a zooplankton database for the Portuguese coast and make it accessible to interested users. In this sense, data processing is minimal, with care taken to control the quality of the data and to standardize the units in which the values are expressed.
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 261 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.
Versions
The table below shows only published versions of the resource that are publicly accessible.
