Deux semaines après le début des opérations, le 2021 CW / SSB DX Ultra-Marathon «Bands Alive» organisé par le True Blue DXers Club a franchi le cap des 400 radioamateurs pré-enregistrés. Cette initiative, inédite dans son format et sa portée, vise à soutenir l’activité en CW et SSB, en profitant du rebond de conditions de propagation avec le début du cycle solaire 25. Compte tenu de la popularité de ce nouveau concours, annoncé début novembre, il est raisonnable de s’attendre à ce que la participation a dépassé la barre des 500, un résultat remarquable, car des initiatives similaires et bien établies rassemblent généralement quelques dizaines de participants.

The vessel, known as ‘Orange Roughy’, completed its last trip among the long list of its scientific expeditions for the Australian Antarctic Division on Dec 12.
Located at 82°00’ South, 155° 00’ West, Siple Coast is the middle portion of the relatively ill-defined coast along the East side of the Ross Ice Shelf. Siple Coast is the grounding line of the West Antarctic Ice Sheet, where the ice meets the ocean and starts to float, becoming the Ross Ice Shelf. It is as far south as the ocean reaches anywhere in the world.
(See location 862AB on the map) This season’s main objective is to develop an understanding of the nature of the sea-floor sediments. Future retrieval of deep sediment cores will help inform multidisciplinary studies of the stability of the Ross Ice Shelf during past warm periods. Drill holes at the Siple Coat will also support the United States Icefin project. Icefin is an under-ice robot designed to explore ice-ocean environments here on Earth and ultimately on Jupiter’s icy moon named Europa.
