Delayed Anthropocene in the deep-sea biosphere: a last paradise soon lost? Abstract. The deep sea remains a last paradise and the place of minimal human impacts compared with other ecosystems. However, this pristine status is rapi

The deep sea has been spared the brunt of anthropogenic harm so far...but that may change if deep-sea mining and/or marine CO2 removal technologies gain steam...

Exciting new work starting in the lab!

It’s live! Now the real work begins…making the BBNJ treaty as strong and effective as possible.

I was humbled to call Kristina a mentor and a friend - she made the complicated world of marine policy legible, and showed me that scientists no longer have the "luxury" of detachment.

We don't need to choose between understanding and protecting the natural world - we can, and should, do both!

An actionable guide to the United Nations' Biodiversity Beyond National Jurisdiction Agreement for research scientists The United Nations' “Biodiversity Beyond National Jurisdiction” (BBNJ) Agreement establishes a broad framework regulating activities—including scientific research—in marine Areas Beyond National Juri...

With a rockstar team of researchers and diplomats, we put together a list of requirements, recommendations, and opportunities for scientists to keep in mind.

Science is at the core of the BBNJ treaty, and scientists have many key roles to play!

The UN's "Biodiversity Beyond National Jurisdiction" treaty (aka the "High Seas Treaty") is about to take effect - great! But what does it mean for scientists working in international waters? What will we need to do to be compliant and, ideally, helpful?

We wrote a paper to answer these questions 👇

Minor contribution of ammonia oxidizers to inorganic carbon fixation in the ocean - Nature Geoscience Ammonia oxidizers contribute minimally to carbon fixation in the dark ocean despite their abundance at depth, according to enzyme inhibition experiments on water samples from two cruises.

Despite their prominence in the deep sea, ammonia oxidizing microbes don't play a huge role in carbon cycling. They're around, just not very active, starved for nitrogen... 🧪🌊

BREAKING: UNL to eliminate multiple programs as part of $27.5 million budget cut Textiles, Merchandising, and Fashion Design and Earth and Atmospheric departments announced the possible elimination of the programs as apart of UNL $27.5 million budget cuts.

And here's the initial news and recent update on the UNL situation 🧪 It's not too late!

I was in geology depts from undergrad through my PhD, and they've given me an expansive sense of time and space as they operate in the natural world. These scales are completely different from our own lived experience, but are essential to understand if we're to exist long-term on this planet. 🧪

Between this and similar news at the University of Nebraska (where the Dept of Earth & Atm Sci has been earmarked for elimination), geology departments seem to be on the front lines of academia budget cuts.

This would be a tragic loss for young scientists and citizens alike 🧪
