1994 Purbeck Marine Research Unit Canford School, Swanage Dorset, Ross Coral Mapping Drift dive transect surveys

All these records relate to "Powell (ed) (1994)  - Ross Coral Mapping Project (Preliminary Report) 1994" A copy of the report is held at English Nature (Dorset Team).
     This survey aimed to map the distribution and record the abundance of Ross coral (Pentapora foliacea) in the area off Swanage between Handfast Point and Ballard Point. The survey confirmed that Ross coral occurs much further east along the English Channel than previously recorded. Due to strong tidal flows in the area, drift dives were used to make transects of the area. 12 dives were undertaken, 10 of which recorded Pentapora, and have been entered on this database. The largest colonies were 30cm or more in diameter and occurred on outcrops of chalk and large boulders in the south western part of the survey area. Within the area investigated, several thousand colonies were recorded, making Ross Coral locally abundant. GPS/Decca navigation was used to pinpoint the position of the dive support boat at the start, during (following the diver's surface marker buoy) and at the end of the dive allowing a habitat map along the line of the dive to be constructed. The survey also highlighted an area of significant marine interest with a species rich animal turf on the chalk and rubble sea floor off Ballard Point. Underwater photography was used to supplement written records and to aid identification of other species. Reference was made to two records further east, off the Isle of Wight, one occurring in water 65-70m deep.

High resolution sonar for the archaeological investigation of marine aggregate deposits

The High resolution sonar for the archaeological investigation of marine aggregate deposits project was undertaken by the University of Southampton and funded through the English Heritage disbursed Aggregates Levy Sustainability Fund. The project investigated the potential of state-of-the-art, high-resolution, sonar systems for the investigation of marine aggregate bodies for archaeological material. This project aimed to tackle fundamental problems to the detailed archaeological investigation of coarse grained aggregate deposits. This aim was achieved through the optimisation of new Chirp sources, developed by the School of Ocean and Earth Science, University of Southampton, in conjunction with GeoAcoustics Ltd, Great Yarmouth, specifically for the penetration of coarse grained materials.

2000 - 2003 Lin Baldock, various sites in Dorset, Dive Log records and observations carried out by Lin Baldock

Records from dives and intertidal visits carried out in from 2000 to 2003 by Lin Baldock within the Dorset area.  Event reference for dives refers to the Dive Code in Lin Baldock's dive log which is held by her.  References for intertidal records refer to dates in field notebook.  The thoroughness of the species lists varies depending on other activities being carried out during the dives.  Particular attention was given to algae in most situations.  Identification was mostly carried out in situ.  However, some smaller species (e.g. filamentous algae, caprellids, small bryozoans and hydroids) were identified using a microscope in the laboratory.  If this was the case it is indicated in the "species qualifier" box as "LAB ID".
     Notes.
     The species pair Aglaothamnion byssoides and Aglaothamnion pseudobyssoides has been recorded throughout as Aglaothamnion pseudobyssoides, hence these records may include both species and ID is marked as uncertain.  The two species are difficult to distinguish in the absence of sexual reproductive structures. Species not included in the Species Directory "Dictionary" have been included in the description for the relevant event.
     Field data and specimens are held by Lin Baldock who retains copyright.

2011 Commercial Fishing: Important areas for fixed salmon netting around Grampian

In order to better understand the nature, extent and intensity of interactions amongst coastal users, Marine Scotland asked the Local Coastal Partnerships to collect spatial data not already represented in national datasets. This map shows important areas for fixed salmon netting around Grampian. It was created by the East Grampian Local Coastal Partnership, and covers the area of sea out to 12 miles. The source was from a local fishermen: one skipper was interviewed, representing the very South of the Region (Gourdon). The fisherman drew on a map areas important to him. The data set is far from complete and consultation with a larger more representative sample size of fishermen is strongly advised.

Digital Archive from The Inner Humber Rapid Coastal Zone Assessment Survey Project, 2019 to 2021

This collection comprises gis and spreadsheets from the Inner Humber Estuary Rapid Coastal Zone Assessment Survey Project which was part of a national programme funded by Historic England. The project was undertaken by Cornwall Archaeological Unit, Cornwall Council, Coastal and Offshore Archaeological Research Services (COARS), and University of Southampton between 2019 and 2021.
     The project consisted of a desk-based assessment of the threat posed to heritage assets by flooding, rising sea levels and increasing rates of coastal erosion.
     The survey area covered 247 sq km; from the lowermost limits of the Rivers Ouse and Trent following the River Humber eastwards to the Patrington Channel on the north bank of the estuary and on the southern bank, to the parish boundary between Great Coates and Grimsby. It included estuary, the intertidal zone out to Lowest Astronomical Tide (and 1km outwards below it), with a 1km 'hinterland' to the landward side of Mean High Water.
     The survey area was sub-divided according to the Flood Areas as set out in the Environment Agency's 2008 Flood Management Strategy for the River Humber, and for the eastern end of the survey area (falling within the outer Humber Estuary), in relation to the Policy Units as set in the Flamborough Head to Gibraltar Point Shoreline Management Plan (2010).
     The Phase 1 Desk-based Assessment assessed the data available on the character of the historic environment and heritage assets within the project area and outlined the potential threats to them in order to design a strategy for Phase 2 (Field Survey) - a draft project design for which was also a product of the project.
     Overall, the project added, updated or amended 686 records to three Historic Environment Records including, the Humber HER (which covers Kingston-upon-Hull and parts of the East Riding of Yorkshire), North Lincolnshire and North East Lincolnshire. The new records created totalled 559 for Humber, 100 for North Lincolnshire and 15 for North East Lincolnshire. Many of the new prehistoric and Romano-British records were added from the findings of previous projects, such as the Humber Wetlands Project, that had not been previously incorporated into the HERs.
     Opportunities for further research, survey and outreach identified by the desk-based assessment are presented in the context of the regional themes and research aims set out in the Yorkshire and East Midlands Research Frameworks. Specific sites and areas which would benefit from further research or work are also summarised in the final report.

2000 The Marine Conservation Society - Seasearch, Various locations in Dorset, Diver observations and detailed survey records

Seasearch records from Dorset in 2000.
     Seasearch is a marine habitat and species recording project for recreational SCUBA divers in the UK. The main aim of these surveys is to gather information on the marine habitats and species surrounding the UK coast, which will assist with their known extent and distribution, and ultimately contribute towards their conservation. Seasearch is co-ordinated nationally by the Marine Conservation Society. Dorset Seasearch has been active since 1995. Original survey sheets are held by Dorset Wildlife Trust, with copies held at Dorset Environmental Records Centre.
     Please note: All of these Seasearch records were originally input into the old Dorset database and were converted over to Marine Recorder v2 in April 2003. The old Dorset database only stored locations as Eastings and Northings values despite entries being made as Lat/Longs. The result is that all these Seasearch records have a Coordinate system of OS ref by default, even though the original paperwork recorded them as Lat/Longs. No accuracy has been lost for the OSGB36 Lat/Longs, as these allegedly translate directly. However, the surveys that used WGS84 Lat/Longs will have a small associated error, so where possible these locations have been re-entered with their original Lat/Longs. Where the Lat/Long datum has not been stated, these records have not been changed as the small error arising from the conversion is believed to be less than the error (~100m) between todays difference between OSGB36 and WGS84 Lat/Longs and the ~100m accuracy error before selective availability was turned off. Please use the Derived from field on the survey event screen to clarify how the location was recorded in the field.

Wrecks on the Seabed / Multibeam Sonar

The Wrecks on the Seabed project tests ways of assessing and evaluating wreck sites to assist with understanding the effects of marine aggregate dredging on shipwrecks. The project is supported by the Aggregate Levy Sustainability Fund as administered by English Heritage. The project has continued through two rounds of the ALSF funding running from 2002 to 2006.
     In all, 20 wrecks have been investigated by Wessex Archaeology using a variety of methods of hydrographic survey, remote sensing and diving survey. The overall aim of the project is to provide industry, regulators and contractors with guidance on the archaeological assessment, evaluation and recording of wreck sites. Such a framework is important when considering the time and cost of marine investigations. The framework also promotes effective communication between industry, regulators and contractors by defining comprehensiveness and detail for differing levels of investigations suggesting specifications for surveys at each level.

1802 - 2003 Dorset Environmental Records Centre, Dorset, Algal records from Biological Records Centre from various sources.

In September 2003 all the Dorset records from the Marine Algae Recording Scheme Database of the British Phycological Society (held at the Biological Records Centre - CEH Monks Wood) were extracted and passed onto Dorset Environmental Records Centre for inclusion in the Dorset Marine Biodiversity Database. 
     The Marine Algae Recording Scheme was launched by the British Phycological Society in conjunction with the Biological Records Centre (BRC) in 1971. The aim of the scheme, organised by Professor T.A. Norton, was to map the distribution of the British seaweeds. It covers all the benthic members of the Chlorophycota, Phaeophycota and Rhodophycota, plus the genus Vaucheria (Xanthophyta). Only attached seaweeds are recorded, drift plants being ignored as their provenance is unknown. A standard recording card was produced at the start of the scheme, and was used for field recording by an enthusiastic group including both professional phycologists and amateur collectors. In addition, records were extracted from the herbarium of the Royal Botanic Gardens, Edinburgh and from papers published since 1950. The accumulated record cards were passed over to the Biological Records Centre in 1982 and put onto computer in 1983-4. The following data were included for each record (if provided by the original recorder): site name, grid reference (in full), date of record, code number of recorder and source of record.
     A Preliminary Atlas of fifteen species was published by the Biological Records Centre in 1978; since then recording has progressed steadily with a Provisional Atlas of 155 taxa published in 1985 and the final atlas published in 2003.
     Due to the age of some of the records, some of the Latin names have been revised since they were recorded. For those species names that weren't recognised by the current species dictionary the latest synonym has been taken from Hardy, G. and Guiry, M. (2003) A Check-list and Atlas of the Seaweeds of Britain and Ireland. A note to this effect has been written in the notes section of the sample screen.
     N.B. All of the records received from the Biological Records Centre have currently been imported, including those with a vague date or a vague 2 figure grid reference. Where the locality name stated for a record allowed it to be pinpointed to a 4 figure grid reference, this has been done and a note added into the Sample description screen. It is hoped that over the coming years, the original source of most of these records can be identified and any additional information extracted and added to this database to add greater accuracy and value to the records.
