Scientific Symposium on
Harmful Algal Blooms and Climate Change
Gothenburg Sweden 19-22 May 2015

A Scientific Symposium on climate change effects on the global distribution, frequency and intensity of harmful Algal blooms will be held 19-22 May 2015, at Gothenburg, Sweden.

The central purpose of this symposium will be to bring together HAB scientists and climate change scientists to ascertain what is known about climate change and its potential linkages to HABs, to identify the most pressing, achievable research goals over the next decade, and to determine the minimal long term monitoring infrastructure needed to provide the data for global HAB assessment in the context of climate change.

About the symposium
Climate change will significantly affect marine ecosystems, and it is expected that there will be effects on the character, frequency and intensity of Harmful algal blooms. Examples of the potential drivers of HAB change include:

·         warming – changed distribution of HAB species, including range expansion/contraction

·         ocean acidification – possibly increased total primary production, positive for some HAB-species

·         increased water column stability – increased stratification favour many HAB-species

·         changes in rain fall distribution and dynamics - altered nutrient supply and input of humic substances, both potential drivers for change in the occurrence of HAB’s

·         + several other ways
However, these anticipated linkages to increases or decreases in HAB impacts remain largely undemonstrated, and it is unlikely that all potential avenues of affect are known. Presentations at the symposium will include findings from observations, experimental work and modelling.

The symposium will include invited speakers, oral and poster presentations by participants, with concentration on participant-led break-out sessions on specific topics.

A second announcement with information on registration, abstract submission etc. will be distributed in early 2015. Information on symposium fee and possibilities for young scientists travel awards also will be part of the second announcement.
Prepare for registration and submission of abstracts in early 2015.
Conveners: Bengt Karlson, Sweden, Mark Wells, USA, Raphael Kudela, USA and Angela Wulff, Sweden, Contact: Bengt.Karlson at smhi.se<mailto:Bengt.Karlson at smhi.se>
