In survival situations people often talk about the rule of three. It is said that humans can only survive for 3 minutes without air, 3 hours without heat, 3 days without water and 3 weeks without food. Not wanting to be left out, it seems that some phytoplankton also obey a rule of 3 according to a new study: they can survive for 3 weeks without key nutrients such as nitrogen and phosphorus.

DEFRA report shows the massive pressure that is being put on UK marine science by commercial interests: from setting the research agenda, to running public services for profit, and the desire to dismantle public bodies such as CEFAS and the Met Office.

If you read my previous post on the interesting article about coccolithophore species-specific growth responses to environmental change, you may have been left wanting to know more about coccolithophores in general. I don’t blame you. Coccolithophores are pretty awesome. Continue reading Chalk talk: Coccolithophores
Some of the most progressive and interesting science happens when experts from different fields come together to tackle the same problem. Recently a group of plankton ecologists teamed up with some palaeontologists to assess how climate change impacts the growth of specific species of coccolithophores, both in modern times and during a period of warming 56 million years ago. They showed that two species of coccolithophore responded very differently to this event. Continue reading Using the past to predict the future of coccolithophores

Dr Leigh (@Dr_Leigh) started a genius Twitter hashtag (#OverlyHonestMethods), allowing scientists to come forward and admit how they might really write those extremely dull method sections if journals gave them complete freedom to be extremely blunt. Here are Words in mOcean’s own marine science suggestions that you may have been temped to include in your papers: Continue reading Overly honest (marine science) methods
Dinoflagellates are large single-celled motile phytoplankton that are extremely widespread and abundant in the ocean. They are astonishing little creatures that – depending on the species – can produce potent neurotoxins, feast on organisms many times larger than themselves (whilst also photosynthesising), travel large distances in search of nutrients, hibernate for up to 100 years, and glow with terrific blue-coloured bioluminesence. So, without further ado, here are five reasons why dinoflagellates are friggin’ awesome: Continue reading 5 reasons why dinoflagellates are friggin’ awesome:
Most of you reading this will be very familiar with the story of how ocean acidification is likely to impact marine calcifying organisms: increased carbon dioxide in the atmosphere is decreasing the pH of the oceans and is proposed to eventually lead to the dissolution of the shells of organisms made from calcium carbonate. It is difficult to work out in the lab, however, exactly what the impact of ocean acidification will be on marine calcifiers, as time pressures favour experiments that only assess short-term acclimation responses of organisms to ocean acidification (rather than long-term potential adaptations). Even when long term experiments have been carried out, they have only looked at the impact of pH change alone (see here), ignoring other relevent variables such as temperature.

After 2 months of packing, planning, prepping, and fretting, I finally boarded a plane to Bermuda in mid August to take part in a research cruise aboard the R/V Atlantic Explorer. This was set to be the third and final research expedition of my PhD, and I had firm plans to tie up some loose ends from previous sampling and to [hopefully] confirm a few hypotheses I’ve been juggling about for the past year. Like any research expedition, we faced a few hurdles with engine troubles and impending tropical storms, but managed to leave port only 2 days late, and were able tack on an extra day of sampling on the end to make up for lost time. All in all there was no harm done, except maybe to my ever-dwindling research training and support grant, which certainly took a few hard knocks with flight changes.

There were over 100 talks at this year’s Challenger 2012 conference. We have already covered four of the keynote lectures by Jorge Sarmiento, David Righton, Ken Buessler and Phyllis Lam. Below are summaries of some of the short talks that took place: Continue reading A selection of short talks from Challenger 2012
