title: (Table 1) Chronology of sediment core GeoB10065-9

description: * The 210Pbxs data of MUC-A and MUC-B reveal the existence of a 10-cm thick sequence of repeated young sediment above 14 cm corrected depth. This can likely be attributed to small-scale deformation and/or sliding processes due to seismic activity that can often occur in an earthquake prone region like Indonesia.

title: (Table T1) Initial water quality conditions for bioassay experiments during Nathaniel B. Palmer cruise NBP09-01 in the Amundsen Sea

description: Nutrient addition experiments were performed during the austral summer in the Amundsen Sea (Southern Ocean) to investigate the availability of organically bound iron (Fe) to the phytoplankton communities, as well as assess their response to Fe amendment. Changes in autotrophic biomass, pigment concentration, maximum photochemical efficiency of photosystem II, and nutrient concentration were recorded in response to the addition of dissolved free Fe (DFe) and Fe bound to different model ligands. Analysis of pigment concentrations indicated that the autotrophic community was dominated by the prymnesiophyte Phaeocystis antarctica throughout most of the Amundsen Sea, although diatoms dominated in two experiments conducted in the marginal ice zone. Few significant differences in bulk community biomass (particulate organic carbon, nitrogen, and chlorophyll a) were observed, relative to the controls, in treatments with Fe added alone or bound to the ligand phytic acid. In contrast, when Fe was bound to the ligand desferrioxamine B (DFB), decreases in the bulk biomass indices were observed. The concentration of the diatom accessory pigment fucoxanthin showed little response to Fe additions, while the concentration of the P. antarctica-specific pigment, 19'-hexanoyloxyfucoxanthin (19'-hex), decreased when Fe was added alone or bound to the model ligands. Lastly, differences in the nitrate:phosphate (NO3- :PO4**3-) utilization ratio were observed between the Fe-amended treatments, with Fe bound to DFB resulting in the lowest NO3- :PO4**3- uptake ratios (~ 10) and the remaining Fe treatments having higher NO3- :PO4**3- uptake ratios (~ 17). The data are discussed with respect to glacial inputs of Fe in the Amundsen Sea and the bioavailability of Fe. We suggest that the previously observed high NO3- :PO4**3- utilization ratio of P. antarctica is a consequence of its production of dissolved organic matter that acts as ligands and increases the bioavailability of Fe, thereby stimulating the uptake of NO3-.

title: (Table 1) Magnetozone boundaries at DSDP Site 68-503

description: The paleomagnetic measurement procedure at Site 503 was similar to that described for Site 502 (See preceding chapter). Each core section was measured with the longcore spinner magnetometer at 10-cm intervals. In addition, one or more discrete samples were taken from each core section for measurement of the total magnetic vector and its stability against progressive AF demagnetization. There were noteworthy differences in conditions at Site 503, however, that affected the quality and interpretation of the magnetic data and require comment. The most serious problem we encountered was the presence of rust scale from the drill string. Although the dark flecks typically were concentrated near the top of every recovered sediment core, they also smeared down a meter or more between the core liner and sediment, even when the sediment showed no indication of drilling disturbance. Individual rust scales proved to be highly magnetic - presumably because they incorporate small pieces of unoxidized metal. The anomalously high remanent intensities, several orders of magnitude above the uncontaminated sediment values, and scattered remanent directions observed in long-core magnetic measurements on many cores from Site 503 could be attributed to the presence of rust scale.

title: Gridded results of swath bathymetric mapping of Disko Bay, Western Greenland, 2007-2008, with links to files

description: We combined swath bathymetry data of two cruises of RV MARIA S. MERIAN and the fishing vessel MV SMILLA in June 2007 and August 2008 into a bathymetric grid of 20x20m grid cell size. This grid was combined with ASTER-GDEM land elevation data and is presented in two projections. The used projections are (1) Latitude-Longitude (latlon) with reference ellipsoid WGS84 and z scale in meters and (2) Universal Transverse Mercator, zone 22 (utm) with reference ellipsoid WGS84 and scale in meters. The format is Network Common Data Format (NetCDF), more specifically, the bf (# 1) GMT native, C-binary format1. This format can be easily used and displayed by programs of the Generic Mapping Tools (GMT), the Geographic Resources Analysis Support System (GRASS), as well as other Geographical Information Systems (GIS) or programs with the capacity to viewing and manipulate gridded data such as Fledermaus. Derived properties such as the gradient of the slope in degrees (slope) and the slope directivity (aspect) are given in the same way. The file names are composed of the kind of data (bathymetry, slope, aspect), the grid spacing, the format and the projection. The format is read e.g. by the GMT command grdinfo. Older versions of GMT may need the format to be specified by adding a "=1" to the file name, e.g. grdinfo test.grd=1. The standard NetCDF subformat used by GMT and MBSytem is "nf (# 18) GMT NetCDF format (float)". A conversion can be performed with the GMT command grdreformat, e.g. grdreformat test.grd=1 test_gmt.grd=18. The import command for GRASS would e.g. be r.in.bin input=test.grd output=test bytes=4 anull=9999

title: (Table 1) Age determination of ODP Hole 175-1084B

description: Mg/Ca analyses of G. bulloides and abundances of N. pachyderma (left coiling) from Ocean Drilling Program (ODP) Leg 175 Hole 1084B in the Benguela coastal upwelling system document lower sea surface temperatures during the Last Glacial Maximum (LGM), Younger Dryas, mid-Holocene, and Little Ice Age in the southeastern Atlantic. Taking into consideration the possible effects of differential carbonate dissolution, the Mg/Ca data indicate Younger Dryas temperatures 2°-3°C cooler than those of the early Holocene and LGM temperatures 4°-5°C cooler than those of the early Holocene. The cool interval during the deglacial period at Hole 1084B matches the timing of Younger Dryas shifts in Cariaco Basin and Greenland Ice Sheet records and that of a nearby alkenone record. Comparison of mid-Holocene cooling at Hole ODP1084B with other high-resolution records of Holocene and last deglacial sea surface temperatures from the tropical Atlantic implies consistent basin-wide changes in atmospheric circulation. A brief period of 1.5°-2°C cooling between 17.8 and 17.2 ka, if related to Heinrich event 1, is consistent with a previously hypothesized tropical origin of all Heinrich climate change events.

title: Experiments on polar seaweeds

description: Organisms populating benthic shallow water systems of both polar regions are adapted to a particularly harsh environment. We studied effects of freezing and the combination of high light intensities and low water temperatures on photosynthesis of key macroalgal species from the Arctic intertidal (Fucus distichus) and Antarctic subtidal (Palmaria decipiens). Photosynthetic activity of F. distichus specimens was monitored during the freezing process; there was a marked decrease in quantum yield with decreasing temperatures, and a rapid recovery as soon as temperatures increased again. Thus, under the experimental conditions tested, no indication of photodamage was found. Specimens of Palmaria were exposed to a combination of high light intensities and low water temperatures. A persistent impairment of photosynthetic activity occurred at 0°C at light intensities of 400 µmol photons m-2 s-1. In all treatments, there was a decreasing ratio of phycobiliproteins to chlorophyll a. Overall, the two studies provide baseline data for interpreting physiological responses of two important macroalgal species in an extreme environment, the polar coastal ecosystem.

title: Gene sequences of the lichen Cetraria aculeata

description: Lichens are symbioses between fungi (mycobionts) and photoautotrophic green algae or cyanobacteria (photobionts). Many lichens occupy large distributional ranges covering several climatic zones. So far, little is known about the large-scale phylogeography of lichen photobionts and their role in shaping the distributional ranges of lichens. We studied south polar, temperate and north polar populations of the widely distributed fruticose lichen Cetraria aculeata. Based on the DNA sequences from three loci for each symbiont, we compared the genetic structure of mycobionts and photobionts. Phylogenetic reconstructions and Bayesian clustering methods divided the mycobiont and photobiont data sets into three groups. An AMOVA shows that the genetic variance of the photobiont is best explained by differentiation between temperate and polar regions and that of the mycobiont by an interaction of climatic and geographical factors. By partialling out the relative contribution of climate, geography and codispersal, we found that the most relevant factors shaping the genetic structure of the photobiont are climate and a history of codispersal. Mycobionts in the temperate region are consistently associated with a specific photobiont lineage. We therefore conclude that a photobiont switch in the past enabled C. aculeata to colonize temperate as well as polar habitats. Rare photobiont switches may increase the geographical range and ecological niche of lichen mycobionts by associating them with locally adapted photobionts in climatically different regions and, together with isolation by distance, may lead to genetic isolation between populations and thus drive the evolution of lichens.

description: The objective of the IMR-2009615 cruise was to study the distribution of fish and plankton in relation to the occurrence of Lophelia cold-water coral reefs and the general topography in the Traena Deep coral reef field. The underwater video footage was taken using the video rig Campod. The Campod is a light weight, three-legged platform equipped with 2 video cameras, hard disk recording, lights (2x400w HMI), depth sensor, altimeter, laser scaling and transponder for positioning. The rig was towed at a speed of 1 knot and was kept 3 meters above the sea-bed. The camera was mounted in a slightly forward looking angle to increase the field view and the chance of observing fish. The towed video camera was deployed 25 times resulting in a total of 23 hours with high definition video records. This dataset contains links to fourty-three (43) video files.
