kosterhavet Bayesian Network
Description
A Bayesian network to inform the management of key species in Kosterhavet National Park under contrasting storylines of environmental change.
Format
A discrete Bayesian network to predict the consequences of human activities for coastal ecosystems and identify areas for directed abatement measures. Probabilities were given within the referenced paper (missing probabilities were given a uniform distribution). The vertices are:
- LeisureBoating
Boats per year in marinas and natural harbors (for natural harbors only high season from Jul. 01 to Aug. 07 considered) within Kosterhavet National Park (Low, Medium, High);
- TrawlingFrequency
Number of trawling events per area and year within Kosterhavet National Park (Low, High);
- MusselCultivation
Extent of oysters and blue mussels farms within Kosterhavet National Park (Low, Medium, High, Very high);
- DevelopedLand
Proportion of developed land in the catchments of marine water bodies (Low, High);
- AgriculturalLand
Proportion of agricultural land in the catchments of marine water bodies (Low, Medium, High);
- TNExchange
Annual net total nitrogen exchange between marine water bodies (Low, Medium, High);
- TPExchange
Annual net phosphorus exchange between marine water bodies (Low, Medium, High);
- RadiativeForcing
Scenarios of radiative forcing till the end of 2100 (Current, RF45, RF85);
- Precipitation
Annual mean precipitation on land within the catchments of marine water bodies (Low, High);
- Discharge
Sum of discharges from rivers and runoff from land into marine water bodies (Low, Medium, High);
- Wind
Maximum summer (Jun.-Aug.) offshore wind speed (Low, Medium, High);
- DIN
Mean winter (Dec.-Feb.) dissolved inorganic nitrogen concentration in surface waters (Low, Medium, High);
- DIP
Mean winter (Dec.-Feb.) dissolved inorganic phosphorus concentration in surface waters (Low, Medium, High);
- POM
Annual mean concentration POM (POC - chl-a) (Low, High);
- NutrientEnrichmentRisk
Dependent on combination of states of DIN, DIP and POM (Low, Medium, High);
- Noise
Noise from leisure boats (Low, Medium, High);
- AnchorDamageRisk
Risk of seafloor in shallow bays being impacted by anchor damage of leisure boats (Low, High);
- WaterTemperatureShallow
Mean summer (Jun.- Aug.) sea surface temperature - depth < 10m (Low, Medium, High);
- Transparency
Mean summer (Jun-Aug) Secchi depth (Low, Medium, High);
- OxygenShallow
Lowest percentile of summer (Jun.-Aug.) oxygen concentration of surface water - depth < 10m (Low, Medium, High);
- OxygenDeep
Lowest percentile of summer (Jun.-Aug.) oxygen concentration of surface water - depth < 60m (Low, Medium, High);
- Turbidity
Amount of dry weight (Low, Medium, High);
- BottomSubstrate
Type of bottom substrate (Soft, Hard);
- SeafloorDisturbance
Benthic quality index (Low, High);
- WaterTemperatureDeep
Mean summer (Jun.- Aug.) sea surface temperature - depth < 60m (Low, High);
- TNLoad
Annual load of total nitrogen to marine water bodies (Low, Medium, High);
- TPLoad
Annual load of total phosphorus to marine water bodies (Low, Medium, High);
- SedimentLoad
Annual sediment load to marine water bodies (Low, Medium, High);
- HabitatQuality
Dependent on combination of states of oxygen (deep), turbidity (deep), seafloor disturbance (Low, Medium, High);
- Cod
Catch per unit effor (Low, Medium, High);
- IntermediateFishPredators
Abundance of intermediate fish predators (e.g. Gobiidae, three-spined stickleback) (Low, Medium, High);
- Mesograzers
Abundance of mesograzers (e.g. amphipods, isopods)(Low, Medium, High);
- FilamentousAlgae
Maximum summer (May-Aug.) cover of filamentous algae in eelgrass meadows (Low, Medium, High);
- Phytoplankton
Mean summer (Jun.-Aug.) chl-a concentration (Low, Medium, High);
- Zooplankton
Strongly responds to phytoplankton with weaker links to temperature and oxygen concentration (Low, Medium, High);
- Prey
Dependent on combination of states of zooplankton and seafloor disturbance (Low, Medium, High);
- Eelgrass
Extent of eelgrass meadows within Kosterhavet National Park (Decrease, No change, Increase);
- NorthernShrimp
Catch per unit effort (Decrease, No change, Increase);
