Dr David Blockley

Marine Ecologist (Benthic Ecology, Oceanography, Data Curation)

David gained his PhD with the Centre for Research on Ecological impacts of Coastal Cities (EICC), University of Sydney, studying anthropogenic structures as habitats for intertidal marine organisms. This lead to a Post-doctoral fellowship within a collaborative research project between the EICC and local and state government agencies, harbour authorities, developers and environmental consultancies, exploring methods in which intertidal seawalls could be built in order to maximise the biodiversity supported by these artificial structures. Following this, he moved into environmental consultancy, focusing on the offshore resource industry. In this role he worked primarily with the oil and gas industry operating in marine environment of Western Australia, monitoring impacts of their offshore operations. He accepted a position with SAERI to coordinate the curation of the benthic, oceanographic and fisheries data. In this role he is collating and reviewing the data that has been gathered from the various benthic, oceanographic and fisheries surveys for storage in a database that can then be used as a valuable resource for environmental decision making and scientific investigations of the maritime environment of the Falkland Islands. In collaboration with key stakeholders he will also be developing strategies to be used for future surveys.

Current Projects

Addressing priority gaps in understanding ecosystem functioning for the developing Falkland Islands offshore hydrocarbon industry – the ‘GAP Project’. David is managing the Benthic ecology, Oceanography, fisheries and Data Curation part of the project. David's primary objective for this part of the project is data collation and curation so that they can be used more efficiently in future EIAs. Organisations operating in the Falkland Islands have collected large amounts of information over the last twenty years and this includes oceanographic, metocean, seismic, benthic fauna, benthic environmental, multi-beam and RoV footage etc. Much of these data are held at different locations and the fate/location of some remains unknown. In order for these data to be used a strategy for data storage, quality control and curation is essential and so David will also be working with collaborating partners within the Falkland Islands Government, the oil and gas industry and the Natural History Museum in London to develop these strategies.
