Introduction Flashcards
First lecture of Light Climate
What is RESICE
Autonomous vehicle to measure key environmental variables, phyto and zooplankton production, biomass and biodiversity
What does CTD detect
Temperature, salinity, depths and Chla
What does the EcoTriplet detect
Chl a, cDOM, TSM
What does the FRRf detect
Photosynthetic parameters, irradiance and Chl a
What does the Arctic ABCD Light observatory detect
1 hour measurments of 180 degree sky image, light intensity (white, R, G, B), Spectral irradiance, polar night irradiance measurements
What is are characteristics for the top layer in the ocean
NPQ, expression of photoprotection genes, high rETR, low alpha, increase PET chain, ROS managment, ROS production, high light
What are characteristics for deeper waters
Decreased photoprotection genes, decreased PET chain rate, decreased ROS production, low light, more LHCF and LHP, low rETR, high alpha
What are the three intervals of twilight
Civil twilight (0 to 6 degrees under horizon) Nautical twilight (between 6 and 12 degrees) Astronomical twilight (between 6 and 12 degrees)
What is a typical food web in Svalbard
Virus-bacteria-phytoplankton-ciliates-copepods
Name 4 ice algea species
Nitzschia frigida
Polarella glacialis
Phaeocystis glacialis
Navicula
Name 4 macroalgae found around Svalbard waters
Fucus distichus
Laminaria solidungula
Sacchoriza dermatodea
Alaria esculenta
Name some red calcarous algal seascape characteristics
Species such as anemones, sea urchins, brittle starts, function in photosynthesis, depths of 50 -60 m
How can we use taxonomy for kelp forest eco physiology
Use morphology, genetics, molecular tools, chemotaxonomy (pigments, proteins, element analysis) to identify map and monitor kelp forest conservation
What are characteristics of kelp forests
Missing zoning pattern, competition for light, nutrients, place to attach, light limitation between 5 to 30 meters
Why is there no zonation in Svalbard waters
Light regime, nutrient, substrate, epigrowth, sedimentation, ice scouring and grazers
