Metadata: Mollusc species type and counts from transects across coral reefs in the Phillippine Archipelago
Abstract:
This dataset consists of measurements of species type, count and size of mollusc species of the coral reefs in the Philippines. Sampling was conducted over four locations in the Philippine archipelago from 23 March 2012 to 19 June 2012. Data were collected through a field survey conducted by snorkelling and diving along a series of replicate transects from the shallow nearshore reef flat to a depth of 15m on the outer reef slope. The molluscs were counted, identified to species and measured (to gauge population structure and reproductive status). These surveys formed the field component of NERC Discovery Science project "Effects of coral reef habitat degradation and overexploitation on gastropod molluscs at the global centre of marine biodiversity". The project aimed to: Determine whether deteriorating quality of habitats in coral reef ecosystems, resulting from anthropogenic and other impacts, coupled with intensive artisanal fishing pressure, leads to a decline in gastropod mollusc abundance and species richness; Establish the trajectory of species loss in relation to these pressures by contrasting reefs within regions that have been degraded and/or exploited to differing extents. NERC Research Grant NE/I015566/1 funded the project. The grant is held by the University of York, Department of Environment and led by Dr Julie Patricia Hawkins. It ran from 01 September 2011 to 31 August 2012. Mollusc size and count data have been received by BODC as raw files and will be processed and quality controlled using in-house BODC procedures before being made available online in the future. Raw files are available on request from BODC Enquiries.

| 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. | Mollusc species type and counts from transects across coral reefs in the Phillippine Archipelago |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | British Oceanographic Data Centre record 1048Coral_Degradation_Philippines |
| 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. | 761242153f585da1b51d33f538d2d355 |
| Resource Identifier | This is the code assigned by the data owner. | EDMED6774 |
| 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 | 2012-03-23 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | This dataset was created by scientists for the 'Effects of coral reef habitat degradation and overexploitation on gastropod molluscs at the global centre of marine biodiversity collision' project, which ran from 2011 to 2012, following their in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for ingestion into one of the schemas of the National Oceanographic Database (NODB). During ingestion BODC undertake quality control, documentation and metadata enhancement procedures appropriate to the type of data. For an overview please see http://www.bodc.ac.uk/about/informationtechnology/dataprocessing_steps/. BODC supply full information about data collection, data processing and data quality with all data requests to enable users to assess data suitability themselves. |
