· Please see Observations
at Funka Bay for an explanation of why
observations are recorded at Funka Bay.
Observations have been recorded
at Funka Bay for several decades. There are many research cases of marine
chemistry as well.
We must identify what
is new relative to conventional research.
Therefore, we utilize
conventional but high-frequency observations with various samples (seawater,
sediments, river water, etc.) and components (nutrient salts, dissolved inorganic carbonate, organic gases, etc.).
It is a brute-force
approach, but a careful arrangement of the obtained data and comparing it with
past research can result in a high-quality analysis.
・We set observation points near
the center of Funka Bay and continued to make oceanographic observations
in February, early March, mid-March, April, May, June, August, October, and
・The diatom bloom occurs from
early March to early April. Hence, this enables us to capture the status
before, during, and after the diatom bloom.
various samples in order to determine geochemical cycles
・We collect water at 0
m and 12 layers from 5-85 cm as well as 10 and 50 cm above the seabed near the center of Funka Bay.
・During the diatom bloom, the diatoms are collected by
pulling vertically with a plankton net.
・We also collect organic particles derived from diatoms
that are deposited on the seabed.
・We also collect water from the Yurappu River flowing into Funka
・We also collect seawater at the estuary of Funka
