explores common interests in marine science contact: gina hebert, marine biological laboratory 508-717-1730; ghebert@mbl.edu woods hole, mass.— hsh prince albert ii of monaco today visited the marine biological laboratory (mbl) in woods hole, where he demonstrated his strong commitment to marine science, exploration, and protection that is the legacy of his great-great-grandfather, the pioneering oceanographer prince albert i. marine biological laboratory interim co-directors neil shubin and melina hale with hsh prince albert ii of monaco. prince albert ii (right) presented the mbl with a sculpture of his great-great-grandfather, the pioneering oceanographer prince albert i. the original is on display in the oceanographic museum of monaco. credit: daniel cojanu/undercurrent productions. his serene highness sailed on the mbl’s research collection vessel, the gemma ; viewed thousands of cephalopods and other marine species in its marine resources center; and received a comprehensive overview of the marine and environmental research to which the mbl has been devoted for more than a century. mbl research complements the mission of the prince albert ii of monaco foundation , which the prince founded in 2006 to take direct action for the protection of nature. the foundation sponsors research, technological innovation, and initiatives for social awareness to limit the impacts of climate change, protect biodiversity, and manage water resources. “our oceans are greatly under threat, despite their size and their vital contributions to humanity,” prince albert ii said during his visit to the mbl. “this is the central issue of our time, an issue that is urgent and at the same time eternal, an issue for today and for future generations. to move forward at the united nations, in monaco, or here on the beautiful new england coast, we have only one resource, and that is knowledge, understanding, and science. our sole resource is all of you.” prince albert ii then announced his foundation’s commitment to funding seabase at mbl, an open-access infrastructure for integrated data on marine organisms, their genomes, their microbiomes, and the environmental status of their habitats. seabase will synthesize critical information for the purpose of understanding and protecting marine biodiversity and ecosystems. “the mbl is grateful for the support of the prince albert ii of monaco foundation in launching seabase,” said mbl interim co-director neil shubin of the university of chicago. “marine ecosystems face increasing threats from habitat loss, pollution, and climate change. understanding the mechanisms that sustain ocean health is an enormous challenge that mbl scientists are well positioned to address by investigating marine organisms and their associated microbiomes, especially changes that signal environmental stress.” prince albert ii attended a panel discussion, “adapting to a climate-changed world,” led by shubin and senior scientists from the mbl ecosystems center. the center is known for its long-term studies of ecological change, particularly in arctic ecosystems and in coastal zones, and for its leadership in advising international policymakers on climate change. coming full circle, prince albert ii ended the visit by viewing original volumes documenting the scientific discoveries of his ancestor, prince albert i of monaco, who devoted much of his life to studying the oceans. also on display was prince albert i’s chair from the l’hirondelle, the first of four research vessels that he built for oceanographic exploration. beginning in 1885, prince albert i led 28 scientific expeditions in the mediterranean and in the arctic, taking biological samplings and oceanographic measures that were published in 65 volumes. the entire set, as well as the l’hirondelle chair, are archived in the marine biological laboratory-woods hole oceanographic institution (mblwhoi) library. —###— the marine biological laboratory (mbl) is dedicated to scientific discovery – exploring fundamental biology, understanding marine biodiversity and the environment, and informing the human condition through research and education. founded in woods hole, massachusetts in 1888, the mbl is a private, nonprofit institution and an affiliate of the university of chicago . large-scale study indicates novel, abundant nitrogen-fixing microbes in surface ocean contact: diana kenney, marine biological laboratory 508-289-7139; dkenney@mbl.edu woods hole, mass.— move over, cyanobacteria! a large-scale study of the earth’s surface ocean indicates the microbes responsible for fixing nitrogen there—previously thought to be almost exclusively photosynthetic cyanobacteria–include an abundant and widely distributed suite of non-photosynthetic bacterial populations. a. murat eren (meren) and tom delmont working with tara oceans data at the university of chicago in 2017. credit: fran jackson the international study, published this week in nature microbiology , was led by a. murat eren (meren) of the university of chicago and the marine biological laboratory (mbl), woods hole, and tom o. delmont of the university of chicago. nitrogen fixation is a critical ecological process in which atmospheric nitrogen is converted to ammonia, making nitrogen “bioavailable” to living organisms to use as a fundamental building block of dna, rna and proteins. “microbes that can fix nitrogen or carbon are at the center of the ecology of microbial communities in many environments, including the surface ocean,” delmont says. “prior to our study, it was thought that the marine microbes responsible for carbon fixation were also largely responsible for fixing nitrogen. it turns out not to be so simple.” “the ability of microbes to fix nitrogen is vital to all life,” says david mark welch, mbl director of research. “this study expands our understanding of the biological diversity of nitrogen fixation by providing the first genomic evidence that non-photosynthetic bacteria on the ocean surface can carry out these reactions.” using anvi’o , a state-of-the-art, open-source bioinformatics platform to analyze metagenomes (the pool of dna sequences that represent all the microbial organisms found in an environment), the team revealed insights into previously unknown marine microbes with nitrogen fixation capabilities affiliated with proteobacteria as well as planctomycetes, a prevalent bacterial phylum that has never been linked to nitrogen fixation before. these newly described microbial populations occur widely and are particularly abundant in the pacific ocean, where they average an estimated 700,000 cells per liter of seawater and up to 3 million cells per liter—orders of magnitude more than previous estimates for non-cyanobacterial n
