Metadata: Water quality of rivers with and without riparian vegetation in rural Brazil, assessed using abiotic parameters and freshwater invertebrate surveys in 2022
Abstract:
Data were collected from sixteen river sites within and around the Iracambi NGO (non governmental organisation) land in Rosario da Limeira, Minas Gerais, Brazil, during the wet season from September 28th to December 18th, 2022. The sites included eight rivers in unprotected areas and eight in protected riparian zones. The dataset includes measurements of abiotic parameters: air and water temperature, salinity, flow rate, pH, dissolved oxygen, nitrate, and rainfall. Freshwater invertebrate biodiversity was surveyed using modified kick sampling, and Biotic Index scores were calculated for identified invertebrate groups.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 10738 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Water quality of rivers with and without riparian vegetation in rural Brazil, assessed using abiotic parameters and freshwater invertebrate surveys in 2022 |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFASca1fead3-b4ea-4efb-9830-43d41af03e0d |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS22162 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2022-09-28 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2022-12-18 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |
| Abstract | The abstract provides a clear and brief statement of the content of the resource. | Data were collected from sixteen river sites within and around the Iracambi NGO (non governmental organisation) land in Rosario da Limeira, Minas Gerais, Brazil, during the wet season from September 28th to December 18th, 2022. The sites included eight rivers in unprotected areas and eight in protected riparian zones. The dataset includes measurements of abiotic parameters: air and water temperature, salinity, flow rate, pH, dissolved oxygen, nitrate, and rainfall. Freshwater invertebrate biodiversity was surveyed using modified kick sampling, and Biotic Index scores were calculated for identified invertebrate groups. |
| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Abiotic parameters were measured in-situ using accessible equipment to ensure ease of use by non-scientific staff. Air and water temperature, and salinity were measured using the TDSTestr probe. Conductivity was determined using the Lutron Intelligent Meter, while nitrates were measured with the LaMotte Octa-Slide Code 1100. Dissolved oxygen was assessed using the LabQuest DO2 probe, and pH was measured with the LabQuest pH probe. Flow rate was calculated using a neutrally buoyant cork and a timer. Rainfall was collected using a modified 1 L plastic bottle with the bottleneck removed. Freshwater invertebrate biodiversity was surveyed using a scoop net with a 5 mm aperture mesh, and Biotic Index scores were calculated for identified groups based on their pollution tolerance. The data were mapped using ArcGIS and analysed statistically using available packages in RStudio. |
