Filed survey on Fukido River mangrove in Ishigaki Island

With the cooperation of the Port and Airport Research Institute, Nakamura (D1) and Phyo (M2) have started to study carbon dioxide sequestration and emission by mangrove forests. In August 2021, they conducted a one-month field survey in the mangroves of the Fukidori River in Ishigaki Island. Fukido River mangrove in Ishigaki Island Mangrove forests are said to have a high carbon sequestration capacity due to carbon sequestration by photosynthesis and the deposition of organic matter by complex above-ground roots. The carbon sequestration is also promoted by the fact that the soil is always in a reducing state due to the high organic matter content, and the rate of soil decomposition […]

HYCOM data download and visualization

The HYCOM database is an oceanic reanalysis dataset often used for open boundary conditions in oceanic circulation models. The Netcdf handling tool of xhycom was developed to facilitate the OPeNDAP download and visualization of Netcdf data using xarray. Data visualization includes creation of still images and time-series movies with matplotlib while interactive visualization with hvPlot. Jupyter Notebook on xhycom may help you to understand how to use it. In terms of visualization, matplotlib is superior in terms of ease of fine tuning and speed, which is better for printed materials. On the other hand, hvPlot is useful for checking values and understanding phenomena interactively; but it is slower.
