July: After much deliberation and because of the high number of cases of Covid in South Africa, and the continued global uncertainty about the pandemic, it has been decided that the ICMGP in 2022 will be held remotely and not in Cape Town. However, it will be held in Cape Town in 2024. Rob will continue to be a member of the executive committees for both the 2022 and 2024 meetings. See here
July: Xiangming boards a research ship in Reykjavik for a cruise which will sample waters and sediment around Iceland to examine the transport of mercury and other metals between the Arctic Ocean and the North Atlantic, and to examine the importance of sediment inputs to the water.
