A sustainable management of the Barents Sea ecosystem is dependent on the period- and phase-relation between lunar-driven biomass variability, and biomass management variability.
A sustainable management of the Barents Sea ecosystem is dependent on the period- and phase-relation between lunar-driven biomass variability, and biomass management variability.
Management of marine eco systems is based on the simple idea: “To predict future biomass, to control the future biomass”. But is future biomass deterministic? If not, we can only explain the past, and future biomass is not controllable.
This research started in 1995. The research question was: “Is there a deterministic period in the Barents Sea marine eco system?”. If so, the period must have an external source. The biomass as an autonomous dynamic system, cannot produce stationary periods, by itself.
The research was presented on a number of international conferences and scientific journal in the time-period from 1996 to 2009. The results showed that:
- Sustainable management of the marin ecosystem is dependent on the period- and phase-relation between lunar-driven periods in the biomass variability and the quota variability.
- The marine eco system has a period- and phase-locked coincidence resonance to the stationary 18.6-year lunar-driven temperature period spectrum.
- The 18.6-year lunar temperature period spectrum is controlled by the 18.6-year lunar nodal tide.
- The 18.6-year lunar nodal tide is controlled by a mutual gravity between the Earth, the Moon and the Sun.
This mean that the Barents Sea eco system is predictable and controllable.
North Atlantic variability
The investigations of North Atlantic Water variability showed that:
- North Atlantic lunar nodal tides: Influences North Atlantic Water inflow to the Norwegian Sea.
- North Atlantic Water inflow to the Norwegian Sea: Influences the climate and rainfall in Scandinavia and the Barents Sea temperature.
- The Barents Sea Kola-section temperature: Influences Arctic ice extent and the Barents Sea eco system recruitments.
- The Arctic ice extent: Influences the North Atlantic Oscillation
- The North Atlantic Oscillation (NAO): Influences the climate, the wether and rainfall in Scandinavia.
- Rainfall in Scandinavia: Influences the energy production in Scandinavia.
Barents Sea eco system
The investigations of Barents Sea eco system showed that:
- The plankton variability: Is period- and phase-locked to North Atlantic Water inflow, controlled by lunar tides.
- North Atlantic cod biomass variability: Is period- and phase-locked to plankton biomass variability. The biomass spanning period has at 18.6/3-year spawning period, in coincidence to the 18.6-year temperature period. The biomass has an optimum spawning period by spawning 2 times in the warm period and 1 time in the cold period. The spawning period causes biomass fluctuations in periods of [18.6/3, 18.6, 3*18.6] years.
- The North Atlantic cod management: History records of biomass estimate introduces a 3-year phase-lag, that may cause a phase-reversal between biomass variability and estimated biomass variability. A 9 year phase-lag in quota management, causes phase-reversal in management, that may lead to a biomass collapse.
- Barents Sea capelin biomass variability: Has a coincidence resonance to the 9.3-year tide. Capelin biomass spanning period has at 3-time coincidence to the 9.3-year tide, which causes a biomass variability of [9.3/3, 9.3, 3*9.3] years. One generation of 9.3/3 = 3.1 years, has a coincidence to a 9.3-year biomass period, which has a coincidence to a 9*9.3-year biomass period.
- The North Atlantic spring spawning haring variability: Has a coincidence resonance to the 9.3-year tide and the 18.6-year tide.
