TL;DR: A north-to-south directionality of the abrupt climatic signal is demonstrated, which is propagated to the Southern Hemisphere high latitudes by oceanic rather than atmospheric processes, which confirms a central role for ocean circulation in the bipolar seesaw.
Journal ArticleDOI
Onset of deglacial warming in West Antarctica driven by local orbital forcing

TL;DR: Results from a new, annually resolved ice-core record from West Antarctica suggest a more active role for the Southern Ocean in the onset of deglaciation than is inferred from ice cores in the East Antarctic interior, which are largely isolated from sea-ice changes.
Journal ArticleDOI
Holocene history of ENSO variance and asymmetry in the eastern tropical Pacific
Matthieu Carré,Julian P. Sachs,Sara Purca,Andrew J. Schauer,Pascale Braconnot,Rommel Angeles Falcon,Michèle Julien,Danièle Lavallée +7 more
TL;DR: A reconstruction of ENSO in the eastern tropical Pacific spanning the past 10,000 years derived from oxygen isotopes in fossil mollusk shells from Peru finds that E NSO variance was close to the modern level in the early Holocene and severely damped ~4000 to 5000 years ago.
Journal ArticleDOI
Hydroxylamine as an intermediate in ammonia oxidation by globally abundant marine archaea
Neeraja Vajrala,Willm Martens-Habbena,Luis A. Sayavedra-Soto,Andrew J. Schauer,Peter J. Bottomley,David A. Stahl,Daniel J. Arp +6 more
TL;DR: It is shown through combined physiological and stable isotope tracer analyses that NH2OH is both produced and consumed during the oxidation of NH3 to NO2− by Nitrosopumilus maritimus, that consumption is coupled to energy conversion, and that NH 2OH is the most probable product of the archaeal AMO homolog.
Journal ArticleDOI
The production of nitric oxide by marine ammonia-oxidizing archaea and inhibition of archaeal ammonia oxidation by a nitric oxide scavenger
Willm Martens-Habbena,Wei Qin,Rachel E. A. Horak,Hidetoshi Urakawa,Andrew J. Schauer,James W. Moffett,E. Virginia Armbrust,Anitra E. Ingalls,Allan H. Devol,David A. Stahl +9 more
TL;DR: These experiments support predictions from kinetic, molecular and biogeochemical studies, indicating that marine nitrification at low ammonia/ammonium concentrations is largely driven by archaea and suggest an important role of NO in the archaeal metabolism.
