SeaExplorer virtual workshop
The open "SeaExplorer virtual workshop" organized for IOPAN will be held online on April 5, 2022 (Tuesday), split in the morning (09:30-12:00) and afternoon (14:00-17:00) sessions. The workshop is aimed in presenting the operational capabilities, available sensor payload, and mission planning and executing of the autonomous underwater vehicle SeaExplorer from ALSEAMAR.
SeaExplorer is a powerful, buoyancy-driven autonomous sensing platform designed to collect water column data profiles with very wide spatio-temporal coverage (thousands of km and weeks to months of endurance). More information can be found at https://www.alseamar-alcen.com/products/underwater-glider/seaexplorer. SeaExplorer is also the first European glider and therefore may offer a good and more affordable alternative to the Slocum and Seaglider platforms.
Workshop is organized by Ilona Goszczko from Observational Oceanography Lab, IOPAN and David Diaz from ALSEAMAR.
The detailed agenda and separate links for the morning and afternoon sessions are provided below.

Webinar: Fluxes and fates of Asian major river derived sediments to the sea
According to program for the Szczecin Marginal Seas Webinars during the Summer Semester 2021/2022 a webinar to be held on March 24, 2022, 2:00 pm (CET).
Please, join online meeting for the lecture: "Fluxes and fates of Asian major river derived sediments to the sea"
to be presented by Prof. Dr. Paul Liu,
Dept. of Marine, Earth, & Atmospheric Sciences, North Carolina State University, USA
Abstract
Recent field studies off the Yellow, Yangtze, Pearl, Mekong, Irrawaddy, and Ganges show less than 50% of these river-derived sediments has been deposited near the river mouth, and rest of them discharges into their adjacent seas. Among those being discharging into the ocean, nearly half of them has been found to be longshore-transported several hundred kilometers from the river mouth. For example, besides the large proximal delta plains near their river mouths, the Yangtze River sediment has been transported ~800 km into the Taiwan Strait, and Yellow River sediment has deposited more than 700 km into the south Yellow Sea. And both the systems have developed a 40-m thick distal mud depocenter. Parallel to the shore, the Mekong-derived sediment has extended >250 km southwestward to the tip of the Ca Mau Peninsula, forming a distal mud depocenter up to 22 m thick, and extending into the Gulf of Thailand. Most recent surveys off the Irrawaddy River Delta indicate, not like other Asian river system, this river disperses its sediments into both east and west sides in the Andaman Sea and Bay of Bengal under different monsoon driving forces. The Ganges-Brahmaputra is the only major Asian river currently delivers a large amount of sediments directly to the deep sea floor via its shelf-cut canyon. This is also true in other large river systems, like the Amazon, Mississippi, and Nile rivers. There is very little or few percent of the total sediment discharge has been found to be across-shelf transported into the deep ocean, except for a few shelves with canyon systems, such as Congo and Ganges. The large distance longshore transport and distribution of the river derived sediments and geochemical elements have some significant bio-geo-chemical impacts on the marine environments. Our most-recent studies of the world major river systems show that, in the past 50 years, sediments from most of world rivers have sharply decreased 80-90% due to the increased human activities (like building dams, overusing water, or sand mining) and climatic changes. Many of those river deltas have been experiencing severe coastal erosions, like the Chao Phraya, Colorado, Indus, Mekong, Mississippi, Nile, Red, and Yellow rivers, etc. Most of these deltas have turned from constructive growing mode to destructive declining mode, for example, the Mekong Delta is now losing ~30 m of its delta per year.

We strongly condemn any military action carried out against a sovereign state.
We strongly oppose the violent attacks against the civilian population.
We declare full solidarity with the Ukrainian people.
As a sign of protest against aggression, the Polish Scientific Committee on Oceanic Research, Polish Academy of Sciences, suspends cooperation with Russian and Belarusian universities and research centers until the end of military operations and the withdrawal of Russian and Belarusian troops from Ukraine.
