West Cumbria Mining – August 2016 – ongoing
Marine environmental surveys in support of planning and marine licence
An ongoing contract for West Cumbria Mining looking at all aspects of their development and how it interacts with the marine environment. This work includes bathymetric charting, scientific beam trawling (fish population study), habitat mapping, physical ocean processes, sediment and water chemical analysis, benthic macrofaunal assessment and numerical modelling. Surveys conducted to date have been undertaken at various sites around the development, including offshore drilling jack-ups and remote onshore and intertidal areas, and thorough health and safety assessments and documentation were completed for each phase/location of survey. Sediment and water samples were collected for a range of analyses (heavy and trace metals, nutrients, sediment radio-isotope analysis, etc.) and stringent protocols were followed in the method of collection, storage, and delivery of these samples to the external laboratory. The scientific beam trawl survey required the in-field identification of fish and invertebrate species. Benthic sediment samples were collected, processed in the field, and analysed at Seastar’s laboratory for macrofaunal identification.
Cefas – June 2023
Berwickshire and North Northumberland Coast SAC
On behalf of Natural England, Cefas commissioned Seastar Survey to undertake a dropdown camera survey of the Berwickshire and North Northumberland Coast SAC in order to verify the extent and distribution of subtidal 'reef' and 'reef like' features. Four Areas within the SAC were surveyed using drop-down video (DDV) techniques. Within each area 10 camera transects of approximately 10 minutes duration were surveyed using high-definition video and high-resolution stills camera. Still images were acquired approximately every 20 seconds throughout each deployment.

Portsea and Hayling Habitat Mapping Survey
A broadscale habitat mapping survey between Portsmouth Harbour and Hayling Island. Planned and carried out a singlebeam bathymetry and sidescan sonar survey and processed and analysed the data acquired. Project managed and organised a sediment sampling survey using a Hamon grab, for subsequent macrofaunal assessment and particle size analysis. The results of the grab survey will be used to ground-truth the acoustic data and EUNIS Level 3 habitat maps will be produced in ArcGIS. A working ArcGIS project will be supplied along with a full report of all findings.
Natural England – February – March 2022
Portland Harbour Lagoon Sandworm
Seastar undertook a sediment sampling survey to determine the presence of lagoon sandworms in Portland Harbour. Liaised closely with staff from Natural England and the National Oceanography Centre to devise a robust sampling and processing method to collect viable lagoon sandworm specimens. Supplied various sediment sampling equipment (e.g. grabs, cores, etc.) and a small survey boat to complete the work. The techniques developed in Portland Harbour were used to collect samples from control sites in the New Forest.
Royal Southern Yacht Club – March – December 2021
MMO Licence Application
MMO Licence application on behalf of the Royal Southern Yacht Club, which required maintenance dredging of their marina. Previous data and licence applications were reviewed and a full application was completed. Sediment samples were collected from within the dredge footprint for subsequent chemical analysis as per the requirements of the MMO Licence application. A singlebeam bathymetry survey was undertaken in order to calculate dredge disposal volumes and a suitable method of dredging and disposal sites were identified.
