UKOA Annual Science Meeting 2012, University of Exeter

12th July 2012

This year's UKOA Annual Science Meeting, attended by over 100 UKOA scientists, was a highly successful forum to discuss OA research and share knowledge between the 7 consortia projects. Each consortia gave presentations about the work they have been undertaking over the last year, enabling information exchange and the development of further collaborative opportunities.

The presentations from the meeting are available below, in order of the meeting programme:

Monday 16th April 2012

Welcome and introduction to UKOA (Harry Elderfield)

Consortia project: What were the effects of rapid ocean acidification events in the Earth’s past?

Have we been here before? (Paul Pearson, Tracy Aze, Paul Bown, Samantha Gibbs)

Consortia project: What are the potential impacts of ocean acidification on the ocean and how it might amplify rising CO₂ and climate change?

Interactions between CO₂, the carbon cycle and climate (Andy Ridgwell, Lauren Gregoire, Jamie Wilson)

Tuesday 17th April 2012

Consortia project: How much variability is there in oceanic CO₂ uptake and what are the trends for the future?

Observations and synthesis to establish pH variability and trends in the open ocean and shelf seas (Andrew Watson, Ute Schuster, Naomi Greenwood, David Pearce, David Hydes, Phil Nightingale)

Consortia project: How will ocean acidification affect the biology of surface ocean communities and biogeochemistry, and how that might feedback to climate?

• Overview including Discovery 366 (Toby Tyrrell)

• Bioassays and size-related impacts (Sophie Richier)

• Carbonate chemistry and environment along the cruise track (Toby Tyrrell)

• Nitrogen cycling impacts (Darren Clark)

• Coccolithophores (Jeremy Young)

• DMS cycling (Frances Hopkins)

• Upcoming cruise: Arctic Ocean, 2012 (Ray Leakey)

• Upcoming cruise: Southern Ocean, 2013 (Geraint Tarling)

• Impacts on particle sinking and ballast (Helen Smith)

• Carbon concentrating mechanisms and CO₂ (Ros Rickaby, Renee Lee)

Consortia project: What are the impacts of ocean acidification on key benthic (seabed) ecosystems, communities, habitats, species and their life cycles?

• Initial results on long-term effects of OA and warming on cold-water corals and coralline algae (Seb Hennige, Penny Donohue, Nick Kamenos, Murray Roberts)

• Long-term physiological responses to elevated CO₂ and temperature in the sea urchin Paracentrotus lividus (Sam Rastrick, Piero Calosi, Helen Findlay, Helen Graham, Chris Hauton, Niki Lacey, Ana Queiros, John Spicer, Nia Whiteley, Steve Widdicombe)

• Impact of long-term OA exposure and elevated temperature on population success in the marine snails Osilinus lineatus and Nucella lapillus (Mike Burrows & Nova Mieszkowska)

• Impact of long-term exposure to high CO₂ and temperature on the physiology and burrowing behaviour of two infaunal invertebrates (Jasmin Godbold, Sam Rastrick, Piero Carlosi, Martin Solan)

• Initial results of long-term OA exposure on the biology of intertidal benthic foraminifera (Nikki Khanna, Jasmin Godbold, David Paterson)

• Effect of elevated CO₂ and temperature on microphytobenthos - preliminary results from the benthic OA flume study (Henrik Stahl, Natalie Hicks, Ashleigh Currie, Emma Defew, David Paterson)

• Physiological adaptation of marine invertebrates to high CO₂/low pH and hypoxia - paradigms and pitfalls (Piero Calosi, Marie Hawkins, John Spicer)

• Scaling-up impacts to predict changes in ecosystem function (Silvana Birchenough, Ruth Parker, Julie Bremner, John Pinnegar, Finlay Scott)

Wednesday 18th April 2012

Consortia project: How will ocean acidification impact ecosystems and chemical cycling in UK and Arctic regional seas?
