This short video explains the Mapping the Deep project at Plymouth University. Mapping the Deep is also part of the UK’s Marine Environmental Mapping Programme (MAREMAP), which aims to achieve common, national objectives in seafloor and shallow geological mapping addressing themes such as habitat mapping, Quaternary science, coastal and shelf sediment dynamics and the assessment of human impacts and geohazards in the marine environment.
The IV International Rhodolith Workshop took place in Granada, Spain in September. Meeting every three years, delegates were from Brazil, Spain, United Kingdom, USA, Ireland, Mexico, New Zealand and Australia, as well as other countries. Rhodolith is a term largely used interchangeably to “maerl,” as free living non-geniculate coralline algae. Researchers came to share the latest research about one of the big four macrophyte dominated benthic communities (others being kelp beds, seagrass meadows and biogenic reefs) (Foster, 2001). Topics included taxonomy, ecology, management and conservation biology, genetics, geochemistry, evolution, palaeoecology, climate change studies and sediment dynamics.
Two excursion took place; the Granada coast to look at living rhodoliths and a two-day excursion to Almería-Cabo de Gata to observe both fossil and living rhodolith beds. The first excursion involved diving off the Granada coast or shorkelling to explore the small sea-caves along the coast. The second excursion involved exploring the processes responsible for deposition of rhodolith debris as cliff-deposits and how they have been preserved across geological time.
