Metadata: 2011, ECON, Zone 2 Firth of Forth, North Sea Offshore Boat Based Mammal Survey
Abstract:
ECON Ecology Ltd were contracted by Seagreen to design and carry out boat based visual surveys of the area for marine mammals and SMRU Ltd were contracted to analyse the marine mammal data from these surveys (May 2010-November 2011). Nineteen months of boat-based surveys for marine mammals have been carried out by ECON Ecology. SMRU Ltd were contracted to analyse the marine mammal data from these surveys. This report presents data on the encounter rate and distribution of sightings of marine mammals from the 19 surveys which took place between May 2010 and November 2011.

| Internal code | Internally assigned metadata identifier | 19760 |
| 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. | 2011, ECON, Zone 2 Firth of Forth, North Sea Offshore Boat Based Mammal Survey |
| 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. | f606bdc7-b164-4f1e-81c1-b8bb12152c3c |
| Resource Identifier | This is the code assigned by the data owner. | CES-400 |
| 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. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2010-05-01 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2011-11-01 |
| 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 survey methodology broadly followed the recommendations set out by Diederichs et al. (2008) for ship-based transect line distance sampling. The main boat used for the survey work was the MV Clupea, a 32 m ex-fisheries research services vessel, operated by IDP, a commercial survey company (Figure 2).The ship platform was stable and the eye-level of the observer was approximately 5 m above sea surface. The ship moved at a speed of approximately 10 knots (5 to 15 knots). One dedicated JNCC-trained observer continuously scanned the area between the boat and the horizon, 90 degrees to each side of the front of the vessel (total range of 180 degrees) with binoculars and naked eye. Every effort was made to ensure that the marine mammal survey was carried out in the most optimal sea conditions available in any single month. Whilst it was not possible to ensure that all days are of sea state 3 or below, the minimum visibility was always over 200m. In accordance with the JNCC standard methods, each sighting was recorded with location (latitude and longitude), time when first observed and time when sighting ended, species, number of animals observed, number of calves/pups, distance from the boat, and bearing and direction of movement. In addition, every sighting record includes identification features, behaviour and other observations (e.g. sex of seals, associations with seabirds etc.). Location of the boat and time during the sighting was recorded instantly using a GPS device. Range is estimated using a range-finder stick and bearing was read from a compass in-built into the GPS device. Field identification of marine mammals was based on the appearance (e.g. dorsal fin, tail fluke, sequence of body parts visible when surfacing, general shape, size and proportions and body markings in cetaceans; shape of head and snout, proportions of facial features in seals) and the behaviour of animals. Detailed observations of marine mammal behaviour and interaction with other mammals and seabirds were recorded according to COWRIE guidelines (Camphuysen et al., 2004). Behaviour was broadly classed into the following: directional swimming (with direction), non-directional swimming, rapid swimming near the surface and resting at the surface (after Diederichs et al., 2008). Additional data recorded continuously during the survey include depth, boat speed, sea state, wind force, wind speed, visibility, glare, precipitation and cloud cover. The numbers of sightings and individuals of each species during each monthly survey were calculated from the data provided by ECON (the file â??FoF MMO MAMMALS MASTER.xlsâ? supplied to SMRU Ltd by Christopher Houston of Seagreen on the 19th December 2011. |
