Effects of Typhoon Chanthu on Marine Chlorophyll a, Temperature and Salinity

open access: yesAtmosphere, 2023
A typhoon is a severe weather process in tropical oceans. Typhoon transit is often accompanied by strong convective weather, such as gales and rainstorms, which threatens fishery, property, and human safety.

Observations of the aerosol particle number concentration in the marine boundary layer over the south-eastern Baltic Sea

open access: yesOceanologia, 2013
Continuous measurements of the aerosol particle number concentration (PNC)in the size range from 4.5 nm to 2 µm were performed at the Preila marine background site during 2008–2009.The concentration maxima in summer was twice the average (2650±50 cm-3 ...

Remote Sensing Inversion of Typical Offshore Water Quality Parameter Concentration Based on Improved SVR Algorithm

open access: yesRemote Sensing, 2023
Chlorophyll a concentration and suspended matter concentration, as typical water quality parameters related to spectral characteristics, are essential for characterizing the degree of eutrophication in water bodies.

Ocean Mover's Distance: Using Optimal Transport for Analyzing Oceanographic Data [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, year 2022, volume 478, number 2262, pages 20210875, 2021
Remote sensing observations from satellites and global biogeochemical models have combined to revolutionize the study of ocean biogeochemical cycling, but comparing the two data streams to each other and across time remains challenging due to the strong spatial-temporal structuring of the ocean.

Lower respiration in the littoral zone of a subtropical shallow lake

open access: yesFrontiers in Microbiology, 2013
Macrophytes are important sources of DOC to littoral zones of lakes, but this DOC is believed to be mostly refractory to bacteria, leading to the hypothesis that bacterial metabolism is different in littoral and pelagic zones of a large subtropical ...

Measuring Leaf Chlorophyll Concentration from Its Color: A Way in Monitoring Environment Change to Plantations [PDF]

open access: yesAIP Conference Proceedings 1554 (1), 210-213 (2013), 2013
Leaf colors of a plant can be used to identify stress level due to its adaptation to environmental change. For most leaves green-related colors are sourced from chlorophyll a and b. Chlorophyll concentration is normally measured using a spectrophotometer in laboratory.
