The SO-AntEco expedition will investigate the diversity of life both inside and outside of the South Orkney Island marine protected area (MPA) region in order to better understand the distribution and composition of the seafloor communities around islands. We will undertake a research cruise that will explore the different seafloor habitats to investigate if different environments support different communities of animals. Understanding where animals that are vulnerable to fishing and other human impacts (such as corals and sponges) live will help us to manage the region’s natural resources in the future.
Understanding the cycling of stable isotopes in coastal Antarctic waters, December 2015 – January 2016
In December and January (2015-2016) Dr Tianyu Chen and Lucie Cassarino took part in the JR15003 cruise on board the RRS James Clark Ross to Marguerite Bay, off the west coast of the Antarctic peninsula. The researchers collected seawater, sediment and particulate samples in order to measure silicon, nitrogen, and neodymium isotopes. The work aims to understand the stable isotope systematics of N and Si, specifically the spatial and temporal variability in biogeochemical cycling and terrestrial inputs into the coastal system. Silicon isotope measurements will take place in the Bristol Isotope Group laboratory, led by Dr Kate Hendry.
N-ICE2015 is a Norwegian-led international program to investigate the effects of the new thin, first year, sea ice regime in the Arctic on energy flux, ice dynamics and the ice associated ecosystem, and local and global climate.The project involved drifting in an ice-strengthened ship with the sea-ice for several months making observations of the sea-ice, seawater, and atmosphere, and measuring a range of physical, chemical and biological properties.The University of Bristol’s contribution is through the analysis of dissolved barium in seawater and sea-ice, led by Kate Hendry and Kim Pyle, in order to trace freshwater inputs in the Arctic. We had some fantastic help in the field from BOPP alumnus Adam Cooper.→Website

Antarctic Sponge Expedition 2015
The Southern Ocean Sponges project is investigating how the not-so-humble sponge can be used to investigate the increasing threat of climate change in the Antarctic. Locked away in sponge skeletons may be the key to understanding past and future environmental change.During February 2015 the sponge team (including Claire Goodwin from the National Museums Northern Ireland, and Jade Berman) sampled several sites along the Antarctic Peninsula to photograph and collect sponges, SCUBA diving from the small 26.5 metre research vessel, the Hans Hansson.→Blog
DIMES is a US/UK field program aimed at measuring diapycnal and isopycnal mixing in the
Southern Ocean, along the tilting isopycnals of the Antarctic Circumpolar Current. Kim Pyle took part in the 2014 DIMES ocean voyage expedition to collect samples for her PhD project.→Website
TROPICS cruise 2013
In 2013 the RRS James Cook carried a group of scientists across the tropical North Atlantic ocean from East to West in order to collect a unique set of sediments and corals.The cruise sampling objectives included such themes as: the controls on coral habitats, the development of geochemical proxies and reconstruction of past climate as well as a number of ancillary studies.→Blog

Corals in the Drake Passage – NPB11-03 expedition
In May 2011 the NBP11-03 expedition carried out sampling of deep water corals spanning the Drake Passage to produce full depth transects. Expedition aims included mapping new areas of the drake passage, determining species distributions (both past and present) and reconstructing seawater radiocarbon depth profiles for the last glacial and deglacial period.→Blog
In April-May 2008 the NBP08-05 expedition carried out sampling of deep water corals in the Drake passage. The cruise aimed to locate and collect deep-sea corals across the Drake Passage that were suited to reconstructing the history of the ocean circulation in the Drake Passage on time scales of tens of thousands of years. This cruise was followed by a more extensive cruise in May 2011 (NBP11-03).→Website
