We write as deeply concerned members of the Antarctic research community after learning of the plan, by the National Science Foundation, to terminate the lease of the Research Vessel/ IceBreaker Nathaniel B.
Palmer in October of this year.
The United States Antarctic Program has had at least one dedicated research vessel operating in the Southern Ocean since 1968.
For those nearly six decades, the N.B.
Palmer and its predecessors have supported world-class science that helped grow the U.S.'s standing as a leader of international scientific research. At the same time, these vessels have provided critical logistical support for the U.S. Antarctic scientific bases. Even as automation and remote observations have increased our
observational capabilities in this harsh region of the world, there's no replacement for a dedicated research vessel that can access remote sea ice-covered regions of Antarctica and that allows sampling of the
of the world, there's no replacement for a dedicated research vessel that can access remote sea ice-covered regions of Antarctica and that allows sampling of the full depth of the ocean and coastal regions on land.
The early loss of the N.B. Palmer is troubling, especially at a time when other nations, including China, Korea, Japan, Britain, and Australia, among others, are increasing their marine capability for Antarctic waters. This decision forecasts the decline of an exceptional history of U.S. scientific contributions. Maintaining a continued US ship-based presence also has strong, strategic and national security geopolitical implications. Antarctica remains a model for international cooperation and peace, with all activities, marine and terrestrial, south of 60°S governed by the 1959 Antarctic Treaty. The treaty, signed by 58 nations, committed all parties to a civilian presence guiding scientific investigation of this remote

Treaty. The treaty, signed by 58 nations, committed all parties to a civilian presence guiding scientific investigation of this remote and fragile part of the world. Today, many nations operate research stations and vessels in the Antarctic. While Antarctica remains remote and a difficult place to access, the modern world allows easier access each year and the number of groups there grows each year, for research, for tourism, for exploitation of fishery stocks, and simply for exerting national presence.
We urge reconsideration of the decision to terminate the lease of the RVIB Nathaniel B.
Palmer, and the continued forward-looking development of the next generation of Antarctic research vessels that will continue US leadership, scientifically and
geopolitically, in the high southern latitudes.
Sincerely,
More than 100 scientists who work in Antarctica or care about having a strong U.S. research presence there have signed a letter calling for the U.S. to keep the Palmer in operation. (4/n)

Functional biogeography of marine microbial heterotrophs
Heterotrophic bacteria and archaea (“heteroprokaryotes”) drive global carbon cycling, but how to quantitatively organize their functional complexity remains unclear. We generated a global-scale unders...

Chlorophyll absorbs a lot more biologically useful solar energy in the ocean than rhodopsins, forming the energy basis of the whole ecosystem.
Actually rhodopsins sometimes absorb more than chlorophyll.

list of banned keywords
🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The value of long-term ecological research for evolutionary insights - Nature Ecology & Evolution
This Perspective discusses using long-term ecological research networks to advance our understanding of fundamental evolutionary processes and evolutionary responses to global change.
Long-term ecological #research projects apart from being highly demanding, it deserves extra respect from the scientific community; funding agencies should consider the benefits of such projects
