Metadata: Nematode assemblages from field-sampling and lab based disturbance experiments from the Exe and Lynher estuaries 1995 - 1997
Abstract:
Data consists of presense data of nematode worms, from both sand and mud habitats, in the form of count data. Data were collected from both the Exe estuary and the Lynher estuary between August 1995 and May 1997. The csv file entitled "nematodesfieldexelynher1995_1997" contains data from field collected sediments. The csv files entitled "nematodesmudlab19951997" and "nematodessandlab19951997" contains data from laboratory experimental treatments sumulating different types of disturbance, including physical disturbance, biological disturbance and organic enrichment. The Read Me describes the conditions of each microcosm from these experiments.

Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 10158 |
| 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. | Nematode assemblages from field-sampling and lab based disturbance experiments from the Exe and Lynher estuaries 1995 - 1997 |
| 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. | CEFAS8aa9c974-9199-41eb-a7c7-05c4feaf2591 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS20354 |
| 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 | 1995-08-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 1997-05-31 |
| 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 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The sampling regions were two intertidal estuaries at the southwest coast of the UK: Exe estuary and Lynher estuary. Bulk sediments (sand and mud) used to seed experimental microcosms. The identification keys used were Platt & Warwick (1983, 1988), Warwick et al. (1998). The experimental data resulted from a series of microcosm experiments designed to examine the differential response of estuarine nematode assemblages. The experiments were conducted from sand and mud habitats to examine different types of perturbation, including physical disturbance, organic enrichment and bioturbation by Carcinus maenas. Intertidal estuarine sediments with their natural meiofaunal communities were collected on 5 occasions between August 1995 and May 1997 from 2 sites in South West England at low tide. Sand was collected from Cockle Sands near the mouth of the Exe estuary at mean low water level. 10 cm diameter cores were used to a depth of 5 cm to transfer sand into a bucket. The sediment had a median particle dia meter of 270 pm (corresponding to the Wentworth grade 'Medium Sand'), with 0% silt/clay (<63 pm). Mud from mid-tide level near Antony at the Lynher estuary was scraped into a bucket from the top 0.5 cm using a spade. The sediment had a median particle diameter of 15 pm (corresponding to Wentworth grade 'Silt'), with 98% silt/clay (Schratzberger and Warwick, 1999). On return to the laboratory, sediment from each site was homogenised by gentle hand-stirring with a large spatula to reduce the initial variability between micro cosms. 300 g of homogenised sand and 150 g of homo genised mud (4 replicates for each type) were fixed in 4% formalin in order to obtain samples of natural nematode assemblages from the field sampling (Schratzberger and Warwick, 1999). |
