title: (Table 1) Sample locations and clay mineral data of sediment surface samples from the Barents Sea region

description: A new surface sediment sample set gained in the western Barents Sea by the MAREANO program has been analysed for basic clay mineral assemblages. Distribution maps including additional samples from earlier German research cruises to and off Svalbard are compiled. Some trends in the clay mineral assemblages are related to the sub-Barents Sea geology because the Quaternary sediment cover is rather thin. Additionally, land masses like Svalbard and northern Scandinavia dominate the clay mineral signal with their erosional products. Dense bottom water, very often of brine origin, that flows within deep troughs, such as the Storfjorden or Bear Island Trough, transport the clay mineral signal from their origin to the Norwegian-Greenland Sea.

description: Molecular formulae were additionally associated with different molecular categories because less than 6% of the DOM has been identified on a molecular level.Molecular categories are defined as follow: 1) dissolved black carbon (BC), with an AImod &gt;= 0.67 (Koch and Dittmar, 2006; doi:10.1002/rcm.2386) was separated in 3 different subgroups, either &lt;15 (BC-&lt;15C), or &lt;=15 (BC-&gt;=15C) C atoms both without heteroatoms, or containing heteroelements (BC-CHOx); 2) polyphenols (poly), with an AImod &gt;0.5 but &lt;0.67; 3) highly unsaturated formulae, with an AImod &lt;0.5, H/C &lt;1.5; 4) formulae of unsaturated aliphatics, with an 1.5&lt; H/C &lt;2, O/C &lt;0.9, N = 0; 5) saturated fatty acids, with an H/C &gt;2, O/C &lt;0.9 and with either no heteroatoms (sat. fatty acids) or with heteroatoms (sat. fatty acids-CHOx); 6) formulae of sugars, with an O/C &gt;0.9 and with either no (sugars) or with heteroatoms (sugars-CHOx) and 7) peptide molecular formulae, with 1.5 &lt; H/C &lt;2, O/C &lt; 0.9 and N &gt;0. Additionally, poly, highly unsaturated and unsaturated aliphatics were further separated in oxygen rich (O-rich) and oxygen poor (O-poor) if the element ratio O/C was &gt; 0.5 or &lt; 0.5 respectively.

title: Parkes observations for project P1317 semester 2024APRS_03

description: The existence of a population of millisecond pulsars (MSPs) in the Galactic bulge is supported, among others, by the Fermi GeV excess, a signal of gamma rays coming from the Galactic center (GC) direction and resembling the cumulative emission of known MSPs. A previous study showed that, while these MSPs are unresolved in gamma rays, some of them could have been detected in past X-ray observations. The authors also identified a large number of MSP candidates among unidentified X-ray sources. By analyzing unpublished radio images, we found interesting radio counterparts to 6 of those candidates, and were granted 20h of observations with the Green Bank Telescope to settle on their nature. We discovered a new MSPs, PSR J1740-2807, towards one of our X-ray targets, bringing to 3 the number of highly-dispersed MSPs in the GC direction and probably unveiling the first direct evidence of a bulge MSP population. We propose to carry out regular timing of this pulsar with Parkes, in order to reveal its properties and potentially claim association with the original X-ray source. The follow up of this source will have a major impact on our understanding of the Fermi GeV excess, but will also benefit the main questions of modern physics like the nature of dark matter, possibly annihilating into gamma rays in the Galactic center, and the equation of state of cold dense matter, which can be constrained from X-ray observations of MSPs.

title: (Table 1) Ice station data during POLARSTERN expeditions ARK-XVIII/2 and ARK-XIX/1 to Fram Strait, the western Barents Sea and north of Svalbard

description: During two expeditions of the R.V. “Polarstern” to the Arctic Ocean, pack ice and under-ice water samples were collected during two different seasons: late summer (September 2002) and late winter (March/April 2003). Physical and biological properties of the ice were investigated to explain seasonal differences in species composition, abundance and distribution patterns of sympagic meiofauna (in this case: heterotrophs &gt;20 µm). In winter, the ice near the surface was characterized by extreme physical conditions (minimum ice temperature: -22°C, maximum brine salinity: 223, brine volume: &lt;=5%) and more moderate conditions in summer (minimum ice temperature: -5.6°C, maximum brine salinity: 94, most brine volumes: &gt;=5%). Conditions in the lowermost part of the ice did not differ to a high degree between summer and winter. Chlorophyll a concentrations (chl a) showed significant differences between summer and winter: during winter, concentrations were mostly &lt;1.0 µg chl a/l, while chl a concentrations of up to 67.4 µmol/l were measured during summer. The median of depth-integrated chl a concentration in summer was significantly higher than in winter. Integrated abundances of sympagic meiofauna were within the same range for both seasons and varied between 0.6 and 34.1×103 organisms /m**2 in summer and between 3.7 and 24.8×10**3 organisms /m**2 in winter. With regard to species composition, a comparison between the two seasons showed distinct differences: while copepods (42.7%) and rotifers (33.4%) were the most abundant sea-ice meiofaunal taxa during summer, copepod nauplii dominated the community, comprising 92.9% of the fauna, in winter. Low species abundances were found in the under-ice water, indicating that overwintering of the other sympagic organisms did not take place there, either. Therefore, their survival strategy over the polar winter remains unclear.
