Dear Friends of Marine Biosphere,

You may witness or heard about the changes occurring in the marine biosphere adjacent to your area recently. Such as the earlier appearance of man-eating sharks (great white shark, Carcharodon carcharias) on your bathing beaches than before, earlier, or later arrival of the school of anchovies, sardines, or mackerel to your fishing grounds than before, or the sudden appearance of macroalgae in a coral reef, etc.

The timings of cyclical or seasonal biological events (phenology), such as migrations, egg laying, flowering, and hibernation are partly influenced by climatic factors that are largely determined by the relative position of the earth to the sun. Due to the rapid climate changes in recent decades, we often observe many abnormalities in the usual times of cyclical biological events or the sudden appearance of new species or the sudden loss of resident species.

IMBeR would like to catalog marine phenological changes in tidal rivers, estuaries, coastal wetlands, lagoons, and offshore areas including oceans. If you wish to report your observations, please report here (in English or in Chinese or in Arabic) and we will provide an expert interpretation as much as possible. We would like to ask you to provide us with information as much as possible, however, we welcome any incomplete information also.
