Description
Cyanobacteria occurrence in lakes from the Azores Archipelago based on data from monitoring programs dated from 1996 to 2018.
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 968 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.

Project Data
The data present here come from samples collected during several monitoring programs developed between 1996 and 2018 which aimed to characterize the biodiversity of inland aquatic ecosystems (lakes and streams) from the islands of Santa Maria, São Miguel, Terceira, Pico, São Jorge, Faial, Flores and Corvo (Azores, Portugal) and to assess the ecological status of these waterbodies using biological quality elements together with physico-chemical and hydromorphological quality elements. These programs contributed to improving the knowledge of cyanobacteria distribution in the Azores, the phytoplankton community structure in regional freshwater ecosystems and the main environmental drivers of aquatic communities in these ecosystems.

Sampling Methods
Phytoplankton samples were taken using Van Dorn bottle and a 10 µm mesh plankton net at lake maximum depth point. In deep lakes (maximum depth > 10 m), until 2010 discrete samples were collected at surface, mid-water column depth and 1 m above sediment. After 2010 a combined sample of the euphotic zone was obtained by mixing discrete 1 L samples collected at 1 m intervals from the surface to the bottom of the euphotic zone. In shallow lakes (maximum depth < 10 m) a surface sample (integrated sample of the first meter of the water column) was collected. Net samples were obtained by a trawl from 1 m above the sediment to the water column surface. All samples were preserved with 1% Lugol solution (v/v) and taxa were identified to the lower taxonomical level possible using light microscopy. Preserved samples after analysis were deposited in Faculdade de Ciências e Tecnologia, Universidade dos Açores.
| Study Extent | Phytoplankton samples from 24 lakes in Corvo (1), Flores (6), Pico (5), and São Miguel (12) islands in the Azores archipelago were collected seasonally between 1996 and 2018. |
