Air-Sea Gas Fluxes and Remineralization From a Novel Combination of pH and O2 Sensors on a Glider

Autor: Luca Possenti, Matthew P. Humphreys, Dorothee C. E. Bakker, Marcos Cobas-García, Liam Fernand, Gareth A. Lee, Francesco Pallottino, Socratis Loucaides, Matt Charles Mowlem, Jan Kaiser

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Accurate, low-power sensors are needed to characterize biogeochemical variability on underwater glider missions. However, the needs for high accuracy and low power consumption can be difficult to achieve together. To overcome this difficulty, we inte

High Resolution pH Measurements Using a Lab-on-Chip Sensor in Surface Waters of Northwest European Shelf Seas

Autor: Victoire M. C. Rérolle, Eric P. Achterberg, Mariana Ribas-Ribas, Vassilis Kitidis, Ian Brown, Dorothee C. E. Bakker, Gareth A. Lee, Matthew C. Mowlem

Publikováno v: Sensors, Vol 18, Iss 8, p 2622 (2018)

Increasing atmospheric CO2 concentrations are resulting in a reduction in seawater pH, with potential detrimental consequences for marine organisms. Improved efforts are required to monitor the anthropogenically driven pH decrease in the context of n

The Mediterranean Sea comprises just 0.8 % of the global oceanic surface, yet considering its size, it is regarded as a disproportionately large sink for anthropogenic carbon due to its physical and biogeochemical characteristics. An underwater glide

Biogeosciences (1726-4170) (Copernicus GmbH), 2022-08, Vol. 19, N. 16, P. 3911-3920

Several trigger mechanisms have been proposed for the onset of the phytoplankton spring bloom. Among these is that phytoplankton cells begin to bloom when they experience higher average light levels in shallower mixed layers, a result of the surface

Release of a Seaglider from an AutoNaut surface vehicle: demonstration mission in the Eurec4a project

Autor: Gillian Damerell, Paul Stafford, Callum Rollo, Karen J. Heywood, Alastair Nichol, Elizabeth Siddle, Ben Webber, Robert Hall, Peter Bromley, Hugh Maclean, Gareth A. Lee, Philip Leadbitter

This PICO presentation describes a recent demonstration mission of our wave-propelled autonomous vehicle, an AutoNaut named Caravela. Caravela has been designed and built to carry and deploy a profiling ocean glider at a specified location and time.

Global oceanic DMS data inter-comparability

Publikováno v: Biogeochemistry, 110(1-3), 147-161. SPRINGER

The global surface seawater dimethylsulphide (DMS) database (http://saga.pmel.noaa.gov/dms/) contains > 50,000 data points and is the second largest trace gas database after carbon dioxide. However, there has been relatively little quality control on

Substrate kinetics of DMSP-lyases in axenic cultures and mesocosm populations of Emiliania huxleyi

Autor: Gill Malin, Michael Steinke, Gareth A. Lee, Claire Evans

Publikováno v: Aquatic Sciences. 69:352-359

Most oceanic dimethyl sulphide (DMS) is produced through the enzymatic cleavage of dimethylsulphoniopropionate (DMSP), a process governed by the activity of DMSP-lyases in algae and bacteria. Laboratory and field experiments with the DMS-producing co

The seasonal cycle of ocean-atmosphere CO2 Flux in Ryder Bay, West Antarctic Peninsula

Autor: Gareth A. Lee, Peter J. Brown, Dorothee C. E. Bakker, Martin Johnson, O. Legge, Hugh J. Venables, Michael P. Meredith

Approximately 15 million km2 of the Southern Ocean is seasonally ice covered, yet the processes affecting carbon cycling and gas exchange in this climatically important region remain inadequately understood. Here, 3 years of dissolved inorganic carbo

Project overruns: why are we still getting it wrong?

Autor: Simon P. Whitaker, Martin Wilkes, Gareth D. Lee

Publikováno v: The APPEA Journal. 57:489

The issue of poor project performance in the oil and gas industry is not new. It has been discussed since the 1980s and, over the past 30 years, there has been considerable effort put into improving project outcomes. As an industry, we have invested

Biogeosciences (BG), 11 (14). pp. 3919-3940.

Coccolithophores are a key functional group in terms of the pelagic production of calcium carbonate (calcite), although their contribution to shelf sea biogeochemistry, and how this relates to environmental conditions, is poorly constrained. Measurem
