Topic 3Development of methods for ocean management in the Japan Sea, an international enclosed coastal sea that includes continental shelves and islands

Outline

The environmental changes in the Tsushima Current medial zone that are caused by global environmental changes and fluctuations in the environment of the East China Sea, and the common and unique aspects of the effect on individual bays, will be determined. In addition, the role of MPA designation in preserving biodiversity will be determined, and integrated land-sea management methods that integrate land areas with sea areas will be proposed. Moreover, methods for integrated management of the Sea of Japan and the Tsushima Current conducted with the cooperation of Japan, China, South Korea, Russia and other nations will be proposed.

Subtopic (1) Proposed management methods for international enclosed coastal seas

Description of Research (FY 2014 – 2015 Achievements)

(1) We conducted a chemical tracer analysis for site data in order to synchronize data on low-order ecosystem models and improve reproducibility accuracy. We provided the results of analysis to each subtopic.
In order to conduct future change prediction tests, we prepared change scenarios for nutrient salt loads from the East China Sea and land sources, based on the management policies in each relevant country.
We compiled the results obtained in Topic 3 and promoted data sharing with each relevant country. We also pursued our work on creating a collaborative organization for joint international management of the Sea of Japan.

Description of Research (FY 2016 Plan)

(1) Based on the results of ecosystem models in Subtopics (2)-1 and 2, and (3) as well as predictions of fuure change, we will study adaptation policies with respect to changes anticipated in the Sea of Japan and prepare proposed management options for the Sea of Japan.
Using Toyama Bay as the target ocean region, we will also begin to verify the effect of management using ecosystem models, in order to determine the effect of management in land areas on low-order ecosystems.

Subtopic (2) 1 Construction of a model to predict environmental changes in the Japan Sea

Description of Research (FY 2014 – 2015 Achievements)

(2) – 1 Using existing ocean observation data, satellite observation data, chemical tracer data provided from Subtopic 1 and so on, we conducted a precise verification of the low-order ecosystem models that had been developed, and worked to determine the response mechanisms of low-order ecosystems in the Sea of Japan.

Description of Research (FY 2016 Plan)

(2) – 1 We will perform numerical simulations regenerative calculation for the past 10 years using the low-order ecosystem models that have been developed in order to conduct precise verification using site data and satellite data, with the aim of determining the causes of changes over time in low-order ecosystems in the Sea of Japan. We will also develop low-order ecosystem models that include the East China Sea in preparation of identifying the influencing factors from the East China Sea.

Subtopic (2) 2 Construction of a model to predict environmental changes in the Japan Sea

Description of Research (FY 2014 – 2015 Achievements)

(2) – 2 We assimilated biological and chemical observation data for chlorophyl, dissolved oxygen and so on into the low-order ecosystem models for the Sea of Japan that were developed during the previous fiscal year. We also revised the major parameters that include transport coefficients for each compartment in the ecosystem, light- and temperature-dependent coefficients, nutrient salt concentrations in rivers and so on.

Description of Research (FY 2016 Plan)

(2) – 2 We will begin work on predictions of future change based on IPCC climate change scenarios and scenarios relating to the nutrient salt load from both land sources and the East China Sea.

Subtopic Leader Naoki Hirose (Professor, Research Institute for Applied Mechanics, Kyushu University)

Subtopic (3) Construction of a higher trophic level ecosystem model for the Japan Sea

Description of Research (FY 2014 – 2015 Achievements)

(3) We worked to determine the form in which material circulation and the response mechanisms of low-order ecosystems in the Tsushima warm current region affect transport and survival in high-order ecosystems (sagittated calamary, snow crab etc.).

Description of Research (FY 2016 Plan)

(3) Based on the results of transport and survival models for sagittated calamary and snow crab, we will verify the ocean regions and times for the establishment of marine protected areas. We will also begin development of a low-order ecosystem model to verify the effect of land-based management on low-order ecosystems, using Toyama Bay as a target ocean region.
