Description of Facility

Outdoor – Pelagic/Benthic – Marine/Brackish

Outdoor infrastructure consisting of 40 independent 600-liter tanks distributed across two marine field stations in the Archipelago Sea (Skärgårdscentrum Korpoström, 20 tanks) and the Åland Islands (Husö Biological Station, 20 tanks), Finland. The systems receive (filtered or unfiltered) through-flowing seawater (brackish conditions, salinities 5–6) from the nearby straights/bays, are computer-controlled for temperature manipulation, and are built flexibly for the manipulation of multiple parameters.

Controlled Parameters
  • Temperature
  • irradiation
  • nutrients
  • artificial light at night (ALAN)
  • (salinity, pH in progress)
Research Topics
  • Climate change (temperature variability and marine heatwave)
  • impacts on single species
  • benthic communities
Facility location(s)
60.1102778,21.598055555555554;60.2794444,19.83138888888889
Primary interests
  • Manipulation of community composition for testing facilitation effects of ecosystem engineer species in climate change (warming, thermal variability, and marine heatwaves) settings.
  • food web approaches
Specialist areas
  • ALAN (artificial light at night)
  • multiple stressors (local, regional, global)
  • the systems can be used in connection to existing wave tanks for the manipulation of waves and water velocity, and/or highly replicated aquarium systems
  • the system is built flexibly encompassing 2×20 600L tanks or the work in experimental sub-units allowing smaller but up to 140 experimental units (20 L)
Equipment
  • 40 independent experimental units (140 to infinite subunits in these tanks)
  • heaters (Schego), coolers (Aqua Medic)
  • internal circulation (EHEIM)
  • flow-through system
  • programmable climate simulation (GHL)
Lodging

Available at the field stations

Korpoström mesocosm tanks are equipped with constant flow and circulation of seawater from the adjacent bay. Electrical cabinets currently provide the possibility for monitoring and manipulation of seawater temperature.
