title: (Table 1) Interstitial water chemistry at DSDP Leg 65 Holes

description: Studies of the chemical composition of interstitial waters obtained at Sites 482, 483, 484, and 485 on DSPP Leg 65 have revealed the following: (1) Early diagenetic processes in these rapidly deposited sediments led to large decreases in dissolved sulfate and concomitant increases in dissolved ammonia and bicarbonate (alkalinity). Associated with these processes of biodegradation of organic matter are carbonate-precipitation reactions leading to minima in dissolved calcium. (2) In Sites 482, 483, and 485 a flux of dissolved calcium from the basalts of Layer 2 into the sediments is implied. This flux is diffusive in nature, and in none of the sites, drilled on very young oceanic crust, is there any evidence for convective motion of pore fluids in the sediment column. (3) As a result of elevated temperatures in the sediments (caused by relatively high heat flow on young oceanic crust), silica diagenesis occurs at a relatively early stage. This diagenesis is associated with processes involving the alteration of volcanic matter in the sediments (low dissolved 87Sr/86Sr), which results in decreases in dissolved silica, magnesium, and potassium, and increases in dissolved calcium, lithium, and strontium.

title: Relative abundance of prokaryotic picoplankton populations in the Atlantic Ocean

description: Members of the prokaryotic picoplankton are the main drivers of the biogeochemical cycles over large areas of the world's oceans. In order to ascertain changes in picoplankton composition in the euphotic and twilight zones at an ocean basin scale we determined the distribution of 11 marine bacterial and archaeal phyla in three different water layers along a transect across the Atlantic Ocean from South Africa (32.9°S) to the UK (46.4°N) during boreal spring. Depth profiles down to 500 m at 65 stations were analysed by catalysed reporter deposition fluorescence in situ hybridization (CARD-FISH) and automated epifluorescence microscopy. There was no obvious overall difference in microbial community composition between the surface water layer and the deep chlorophyll maximum (DCM) layer. There were, however, significant differences between the two photic water layers and the mesopelagic zone. SAR11 (35 ± 9%) and Prochlorococcus (12 ± 8%) together dominated the surface waters, whereas SAR11 and Crenarchaeota of the marine group I formed equal proportions of the picoplankton community below the DCM (both ~15%). However, due to their small cell sizes Crenarchaeota contributed distinctly less to total microbial biomass than SAR11 in this mesopelagic water layer. Bacteria from the uncultured Chloroflexi-related clade SAR202 occurred preferentially below the DCM (4-6%). Distinct latitudinal distribution patterns were found both in the photic zone and in the mesopelagic waters: in the photic zone, SAR11 was more abundant in the Northern Atlantic Ocean (up to 45%) than in the Southern Atlantic gyre (~25%), the biomass of Prochlorococcus peaked in the tropical Atlantic Ocean, and Bacteroidetes and Gammaproteobacteria bloomed in the nutrient-rich northern temperate waters and in the Benguela upwelling. In mesopelagic waters, higher proportions of SAR202 were present in both central gyre regions, whereas Crenarchaeota were clearly more abundant in the upwelling regions and in higher latitudes. Other phylogenetic groups such as the Planctomycetes, marine group II Euryarchaeota and the uncultured clades SAR406, SAR324 and SAR86 rarely exceeded more than 5% of relative abundance.

title: (Table 1) Geochemistry of sector-zoned crystal at DSDP Hole 45-395A

description: Variations in crystal morphologies in pillow basalts and probable sheet flows sampled from the region of the East Pacific Rise drilled during Leg 54 are related both to differences in composition and to an extreme range of cooling rate experienced upon extrusion. The basalts range in composition from olivine-rich tholeiites to tholeiitic ferrobasalts, and include some more alkaline basalts. The kinetics of crystal growth in some samples appears to have been influenced by the amount of initial superheating (or supercooling) of the magma, or possibly by differential retention of volatiles. Olivine in quartznormative ferrobasalts apparently formed metastably at high undercooling. Despite these effects, reliable petrographic criteria are established to distinguish the principal rock types described regardless of the crystallinity and grain size. Microphenocrysts formed prior to pillow formation correspond closely to mineral assemblages inferred from normative plots and variation diagrams to control crystal fractionation at various stages. The details of spherulitic and dendritic growth also provide some clues about composition. Petrographic evidence for magma mixing is scant. Only some Siqueiros fracture zone basalts contain zoned plagioclase phenocrysts with glass inclusions similar to those used to infer mixing among Mid-Atlantic Ridge basalts. All basalts from the summit and flanks of the East Pacific Rise are aphyric. One possible petrographic consequence of mixing between olivine tholeiites and ferrobasalts - formation of clinopyroxene phenocrysts - is not evident in any fracture zone or Rise crest basalt. Highly evolved ferrobasalts with liquidus low-Ca clinopyroxene have not been sampled, nor does textural evidence indicate that any basalts sampled are hybrid compositions between such magmas and less fractionated compositions. Evidently the sampled ferrobasalts are close to the most evolved compositions that occur in any abundance on this portion of the East Pacific Rise.

title: Rapid ablation zone expansion amplifies north Greenland mass loss: modelled (RACMO2) and observed (MODIS) data sets

description: Since the early 1990s, the Greenland ice sheet (GrIS) has been losing mass at an accelerating rate, primarily due to enhanced meltwater runoff following an atmospheric warming of ~1ºC. Here we show that a pronounced latitudinal contrast exists in the GrIS response to recent warming. The ablation area in north Greenland expanded by 46%, almost twice as much as in the south (+25%), significantly increasing the relative contribution of the north to total GrIS mass loss. This latitudinal contrast originates from a different response to the recent change in large-scale Arctic summertime atmospheric circulation, promoting southwesterly advection of warm air towards the GrIS. In the southwest, persistent high atmospheric pressure reduced cloudiness, increasing runoff through enhanced absorption of solar radiation; in contrast, increased early-summer cloudiness in north Greenland enhanced atmospheric warming through decreased longwave heat loss. This triggered a rapid snowline retreat, causing early bare ice exposure, amplifying northern runoff.The data set includes:5.5 km data: annual mean summertime (June-July-August) shortwave down/upward radiation (swsd/swsu; W m-2), longwave down/upward radiation (lwsd/lwsu; W m-2), surface albedo (alb; unitless) and cloud content (qci; kg m-2) modelled by RACMO2.3p2 at 5.5 km spatial resolution for the period 1958-2017.1 km data: annual cumulative meltwater runoff (kg m-2 or mm w.e.) modelled by RACMO2.3p2 at 5.5 km resolution and further statistically downscaled to 1 km for the period 1958-2017. Annual maximum bare ice extent (unitless) remotely sensed by MODIS at 1 km spatial resolution for the period 2000-2018. Mask file at 1 km resolution including longitude/latitude coordinates and outlines of the seven Greenland ice sheet sectors investigated in the study.Additional RACMO2.3p2 data, including daily downscaled surface mass balance (SMB) components at 1 km and modelled climate variables at 5.5 km resolution, are freely available from the authors upon request and without conditions.

title: Model results of orbital forcing and solar activity during the Holocene in NetCDF format

description: In this study we investigate the impact of mid- and late Holocene orbital forcing and solar activity on variations of the oxygen isotopic composition in precipitation. The investigation is motivated by a recently published speleothem d18O record from the well-monitored Bunker Cave in Germany. The record reveals some high variability on multi-centennial to millennial scales that does not linearly correspond to orbital forcing. Our model study is based on a set of novel climate simulations performed with the atmosphere general circulation model ECHAM5-wiso enhanced by explicit water isotope diagnostics. From the performed model experiments, we derive the following major results: (1) the response of both orbital and solar forcing lead to changes in surface temperatures and d18O in precipitation with similar magnitudes during the mid- and late Holocene. (2) Past d18O anomalies correspond to changing temperatures in the orbital driven simulations. This does not hold true if an additional solar forcing is added. (3) Two orbital driven mid-Holocene experiments, simulating the mean climate state approximately 5000 and 6000 yr ago, yield very similar results. However, if an identical additional solar activity-induced forcing is added, the simulated changes of surface temperatures as well as d18O between both periods differ. We conclude from our simulation results that non-linear effects and feedbacks of the orbital and solar activity forcing substantially alter the d18O in precipitation pattern and its relation to temperature change.
