East Atlantic Pattern Drives Multidecadal Atlantic Meridional Overturning Circulation Variability during the Last Glacial Maximum, link to netCDF files, supplement to: Song, Zhaoyang; Latif, Mojib; Park, Wonsun (2019): East Atlantic Pattern Drives Multidecadal Atlantic Meridional Overturning Circulation Variability During the Last Glacial Maximum. Geophysical Research Letters, 46(19), 10865-10873

Zhaoyang Song, Mojib Latif & Wonsun Park
The variability of the Atlantic Meridional Overturning Circulation (AMOC) and its governing processes during the Last Glacial Maximum (LGM) is investigated in the Kiel Climate Model (KCM). Under LGM conditions, enhanced multidecadal AMOC variability is simulated relative to a preindustrial control run and surface heat flux variability linked to the East Atlantic pattern the primary driver of AMOC variability. In contrast, the multidecadal AMOC variability in the preindustrial control simulation is mainly driven by surface...

Anabel von Jackowski & Anja Engel

Neodymium isotopes from water bottle samples measured during METEOR cruise M121 (GEOTRACES cruise GA08), supplement to: Rahlf, Peer; Hathorne, Ed C; Laukert, Georgi; Gutjahr, Marcus; Weldeab, Syee; Frank, Martin (2020): Tracing water mass mixing and continental inputs in the southeastern Atlantic Ocean with dissolved neodymium isotopes. Earth and Planetary Science Letters, 530, 115944

Peer Rahlf, Martin Frank & Ed C Hathorne
In contrast to the vigorous deep ocean circulation system of the north- and southwestern Atlantic Ocean, no systematically sampled datasets of dissolved radiogenic neodymium (Nd) isotope signatures exist to trace water mass mixing and provenance for the more restricted and less well ventilated Angola Basin and the Cape Basin in the southeastern Atlantic Ocean, where important parts of the return flow of the Atlantic Meridional Overturning Circulation are generated. Here, to improve our understanding of...

Planktic foraminiferal test size and size normalised weight from IODP site U1313, ODP site 999 and DSDP site 610 during the Pliocene, supplement to: Todd, Chloe; Schmidt, Daniela N; Robinson, Marci M; De Schepper, Stijn (accepted): Planktic foraminiferal test size and weight response to the late Pliocene environment. Paleoceanography and Paleoclimatology

Chloe Todd, Daniela N Schmidt, Marci M Robinson & Stijn De Schepper
Atmospheric carbon dioxide (pCO2atm) is impacting the ocean and marine organisms. To assess potential impacts of climate change on carbonate production in the open ocean, we measured size and weight of planktic foraminifers during the late Pliocene at pCO2atm concentrations comparable to today and temperatures 2 to 3 °C warmer. Size of all foraminifers was measured at Atlantic Ocean DSDP Site 610, ODP Site 999, and IODP Site U1313. Test size was smaller during the...

Iron limitation of microbial phosphorus acquisition from METEOR cruise M116, supplement to: Browning, Thomas; Achterberg, Eric Pieter; Yong, Jaw C; Rapp, Insa; Utermann, Caroline; Engel, Anja; Moore, C M (accepted): Iron limitation of microbial phosphorus acquisition in the tropical North Atlantic. Nature Communications, 8(1)

Thomas Browning, Eric Pieter Achterberg, Jaw C Yong, Insa Rapp, Caroline Utermann, Anja Engel & C M Moore
Here we demonstrate enhanced natural community APase activity following iron amendment within the low zinc and moderately low iron Western North Atlantic. In contrast we find no evidence for trace metal limitation of APase activity beneath the Saharan dust plume in the Eastern Atlantic. Such intermittent iron limitation of microbial phosphorus acquisition provides an additional facet in the argument for iron controlling the coupling between oceanic nitrogen and phosphorus cycles.

UAV-derived orthomosaic over a small intertidal coastal strip within "El Soldado", estuary in Guaymas, Sonora, México

Miguel Sebastián Encinas-Lara & Luis Arturo Mendez-Barroso
An orthomosaic image was created with a set of aerial photographs taken with commercial grade Unmanned Aerial Vehicle (UAV, 3DR solo) that flew at 30 meters above ground in March 02, 2019 at 9 a.m. (UTC - 07:00). The orthomosaic covers an area of approximately 18,800 m2 where a meteorological tower and eddy-covariance instrumentation were deployed. The data were used to support the project: "Caracterización de los almacenes y flujos de carbono en pastos marinos...

Cyclostratigraphic calibration of the Famennian stage (Late Devonian, Illinois Basin, USA), supplement to: Pas, Damien; Hinnov, Linda A; Day, James E; Sinnesael, Matthias; Kodama, Kenneth; Liu, Wei (2018): Cyclostratigraphic calibration of the Famennian stage (Late Devonian, Illinois Basin, USA). Earth and Planetary Science Letters, 488, 102-114

Damien Pas, Linda A Hinnov, James E Day, Matthias Sinnesael, Kenneth Kodama & Wei Liu
The Late Devonian biosphere was affected by two of the most severe biodiversity crises in Earth's history, the Kellwasser and Hangenberg events near the Frasnian–Famennian (F–F) and the Devonian–Carboniferous (D–C) boundaries, respectively. Current hypotheses for the causes of the Late Devonian extinctions are focused on climate changes and associated ocean anoxia. Testing these hypotheses has been impeded by a lack of sufficient temporal resolution in paleobiological, tectonic and climate proxy records. While there have been...

Allele shift under laboratory selection and local adaptation to low salinity in Baltic Sea mytilid mussels

Loreen Knöbel, Jennifer C Nascimento Schulze, Trystan Sanders, Dominique Zeus, Jörn Thomsen, Claas Hiebenthal, Francisco R Barboza, Heiko Stuckas & Frank Melzner
Baltic blue mussels colonise and dominate benthic habitats with much lower salinity than any other marine mytilid population globally. Surprisingly, all Baltic populations are hybrids of Mytilus edulis x M. trossulus genotypes with the former dominating hybrid genotypes in the western (high salinity) and the latter in the eastern part of the Baltic (low salinity). Here, we tested if low salinity selects for M. trossulus dominated hybrid genotypes and whether populations along the salinity gradient...

Surface ice velocity, radar backscatter and frontal changes - links to datafiles, supplement to: Vijay, Saurabh; Khan, Shfaqat Abbas; Kusk, Anders; Solgaard, Anne M; Moon, Twila; Bjørk, Anders Anker (2019): Resolving Seasonal Ice Velocity of 45 Greenlandic Glaciers With Very High Temporal Details. Geophysical Research Letters

Saurabh Vijay, Shfaqat Abbas Khan, Anders Kusk, Anne M Solgaard, Twila Moon & Anders Anker Bjørk
Seasonal glacier ice velocities are important for precisely estimating annual ice discharge and understanding controlling mechanisms, but these measurements for a large number of Greenlandic glaciers are limited by low temporal resolution. We present seasonal changes in ice velocities, radar backscatter to mark the onset and extent of melt season and ice front positions of 45 Greenlandic glaciers using Sentinel-1 SAR data for the period 2015-2017. Seasonal velocity fluctuations of roughly half of the glaciers...
