title: Longitudinal monthly surveys of water parameters, nutrient, and gas samples in the Coffs Creek estuary, 2017-2018

description: Longitudinal monthly surveys were performed on eleven occasions from July 2017 to June 2018. A total of 66 samples were collected over a total period of 12 months. Water parameters, nutrient, and gas samples were taken approximately every month (excluding September 2017) from the upper water column at 6 sites along the creek salinity gradient at low tide, from the estuary's mouth, and to the upper freshwater creek. A calibrated YSI EC300A was used to measure salinity (±0.02), whilst a calibrated Hach HQ40D measured DO (±0.2 mg/L) and water temperature (±0.10°C). Nutrient samples (including duplicates), filtered and unfiltered, were collected with a sample-rinsed 60 mL polyethylene syringe. Samples for dissolved organic carbon (DOC) analysis were filtered using pre-combusted 0.7 µm GF/F filters (Whatman), into 40 mL borosilicate vials (USP Type I). Samples for nitrogen were immediately filtered using Satourious ™ 0.45μm cellulose acetate syringe filters into 10 mL polyethylene sample tubes. All samples were kept in a cold icebox, away from light, for less than 5 hours and then frozen until laboratory analysis. Nutrient analysis of DOC was performed with the 40 mL borosilicate vials (USP Type I) first treated with 30 µL of H3PO4 before analysis using an Aurora 1030W TOC Analyser (Thermo Fisher Scientific, ConFLo IV). Nutrient analysis of ammonium (NH4+), NOx (nitrate plus nitrite), and total dissolved nitrogen (TDN) was performed on the 10 mL polyethylene sample tubes colourimetrically using a Lachat Flow Injection Analyser. Total dissolved nitrogen and dissolved inorganic nitrogen were calculated from the nitrogen samples. N2O samples were obtained directly from the creek with two replicate 250 mL borosilicate bottles, filled from 20 cm below the surface, ensuring zero headspace, and then immediately treated with 200 µL of HgCl2 solution and capped. The borosilicate bottles were taken to the laboratory for gas extraction where the bottle was inverted to add 60 mL of zero-air (of known N2O concentration) headspace using a needlepoint syringe while simultaneously extracting 60 mL of sample, before being shaken for 4 minutes. Next, 60 mL of gas was extracted from the bottle, while 60 mL of sample was replaced. The subsequently extracted gas was transferred to a gasbag and diluted with 200 mL of known N2O concentration zero-air ready for analysis. The gasbags were analysed for N2O using cavity ringdown spectroscopy on a calibrated Picarro G2308.

title: Tab. 1: Rates of advance of the frontal push-moraines of 19 lobes in front of an approx. 4.5 km long margin of the Kötlujökull

description: In the last years masses of ice, about 5 km long, have been protruding from the lowest part of an advancing glacier margin of the Kötlujökull in Southern Iceland. In the summer of 1983, they appeared as sediment-covered lobes, 10-60 m long, bordering the glacier rnargin like agarland. 1 to 3 push-rnoraines without ice core, rnostly sickle-shaped, occured first in the frontal parts of the lobes: behind thern came several ice-cored moraines with heights of up to several metres. The active ice in front of the precipice of the glacier is called the "glacier-foot" in this paper. The digging out of 9 lobes and the measuring of the advance of 19 lobes showed that in most cases this glacierfoot had split up at its distal end into several plate- or stem-shaped pieces of ice which were situated one upon the other, separated by moraine deposits and proceeding irregularly into the foreland at the rate of several mm/h, The sometimes different rate of advance in the same lobe and different rates of advanee in adjoining lobes (some being entirely inactive) point to a type of rnovement which is independent of the general advance of the glacier. Research in the winter of 1983/84 showed less activity in 3 examined lobes, but the activity had not ceased. The advancement of the lower parts of the glacier-foot into and across the sands of the foreland implies the following genesis of pushmoraines: Shoving off a plate of sand, folding it and pushing it over the foreland at average rates of up to 7,2 mm/h, according to the investigations in thc summer of 1983. At a certain stage of the folding process, new folds begin to develop in front of the old, and the old folds are shifted onto the backslope of thc folds in front of them until they are completely unired. In this way, "püe-moraines" arise, which become higher and higher. They include two or more folds declining towards the glacier. Systems of small moraines presumably of the same genesis occur on old moraine areas in front of the Kötlujökull. The possible cause of formation of a glacier-foot is discussed, and the moraines of the Kötlujökull are compared with certain pleistocene push-moraines.

title: Compound-specific hydrogen and carbon isotopes in sedimentary leaf wax n-alkanes of Lake Dendi

description: Northern Africa's past hydroclimate is characterized by a prolonged humid period known as the African Humid Period (AHP), giving origin to the "Green Sahara" and supporting human settlements into areas that are now desert. The spatial and temporal extent of climate change associated with the AHP is, however, subject to ongoing debate. Uncertainties arise from the complex nature of the African climate, which is controlled by the strength and interactions of different monsoonal systems, resulting in meridional shifts in rainfall belts and zonal movements of the Congo Air Boundary (CAB), associated with changes in dominant moisture sources. Here, we examine a ~12,500-year record of hydroclimate variability from Lake Dendi, East Africa, based on a combination of plant-wax-specific hydrogen (δD) and carbon (δ13C) isotopes. In addition, pollen data from the same sediment core are used to investigate the response of the local vegetation to changing climate conditions. Our δD record indicates high precipitation during the peak AHP (from ca. 10 to 8 ka BP) followed by a gradual transition towards a drier late Holocene climate. Likewise, vegetation cover changed from predominant grassland towards an arid montane forest dominated by Juniperus and Podocarpus trees accompanied by a general reduction of understory grasses. This trend is corroborated by δ13C values pointing to an increased contribution of C3 plants during the mid- to late Holocene. Peak aridity occurred around 2 ka BP, followed by a return to a generally wetter climate (indicated by higher Podocarpus and lower Juniperus pollen values) possibly linked to enhanced Indian Ocean Monsoon strength. Starting at around 1 ka BP, increased anthropogenic activity, i.e. deforestation and agriculture is indicated by the pollen data, in agreement with intensified human impact recorded for the region. The magnitude of δD change (ca. 40‰) between peak wet conditions and late Holocene aridity is in line with other regional δD records of East Africa. The timing and pace of aridification parallels those of African and Indian monsoon records indicating a gradual response to local insolation change. Our new record combining plant-wax δD and δ13C values with pollen highlights the sensitive responses of the local vegetation to precipitation changes in the Ethiopian highlands. Our results also stress that information on local vegetation structure is important when interpreting hydroclimate change.

title: Unshielded precipitation gauge collection efficiency with wind speed and hydrometeor fall velocity

description: Collection efficiency transfer functions that compensate for wind-induced collection loss are presented and evaluated for unshielded precipitation gauges. Three novel transfer functions with wind speed and precipitation fall velocity dependence are developed, including a function from computational fluid dynamics modelling (CFD), an experimental fall velocity threshold function (HE1), and an experimental linear fall velocity dependence function (HE2). These functions are evaluated alongside universal (KUniversal) and climate-specific (KCARE) transfer functions with wind speed and temperature dependence. Transfer function performance is assessed using 30-minute precipitation event accumulations reported by unshielded and shielded Geonor T-200B3 precipitation gauges over two winter seasons. The latter gauge was installed in a Double Fence Automated Reference (DFAR) configuration. Estimates of fall velocity were provided by a Precipitation Occurrence Sensor System (POSS). The CFD function reduced the RMSE (0.08 mm) relative to KUniversal (0.20 mm), KCARE (0.13 mm), and the unadjusted measurements (0.24 mm), with a bias error of 0.011 mm. The HE1 function provided a RMSE of 0.09 mm and bias error of 0.006 mm, capturing well the collection efficiency trends for rain and snow. The HE2 function better captured the overall collection efficiency, including mixed precipitation, resulting in a RMSE of 0.07 mm and bias error of 0.006 mm. These functions are assessed across solid and liquid hydrometeor types and for temperatures between -22 °C and 19 °C. The results demonstrate that transfer functions incorporating hydrometeor fall velocity can dramatically reduce the uncertainty of adjusted precipitation measurements relative to functions based on temperature.

title: Composition of Broken Ridge samples (Table 1)

description: The Broken Ridge tilted and truncated sequence of middle Eocene to Turanian calcareous sediments with intercalated basaltic ash layers is characterized by diagenetic alteration. The level at which opal-CT forms from volcanic glass and the opal-CT/quartz boundary shows that this alteration increases in intensity with stratigraphic depth and is not related to depth below the seafloor. Thus, the rocks were altered before they were tilted and truncated. The preservation of the pre-rift alteration history may be a function of the rapid uplift and erosion following the initiation of spreading between Broken Ridge and the Kerguelen Plateau. The geothermal gradient at the time of rifting, deduced from the pattern of silica diagenesis, agrees with results from present-day heat-flow measurements and suggests that there was no large thermal anomaly at Broken Ridge that time.
description: At Site 753, stratigraphic depth = mbsf; at Site 752, stratigraphic depth = mbsf + 77 m; at Site 754, stratigraphic depth = mbsf + 342 m; at Site 755, stratigraphic depth = mbsf + 1091.5 m. These transformations assume that 190 m of the section is missing between Sites 753 and 752, that there is a 20-m overlap between Sites 752 and 754, and that 460 m of the section is missing between Sites 754 and 755.

title: Abundance of mesozooplankton in the north-eastern Black Sea during SESRU01 cruise in April 2008

description: The SESRU01_mesozooplankton dataset contains data collected in April 2008 at 19 stations located between 37°E and 39.5°E and between 42.4°N and 44.5°N in the north-eastern Black Sea. Samples were collected with a Juday net (mesh size 180 m, mouth area 0.1 m**2). Integrated samples were taken from the lower boundary of the oxic zone to the surface, stratified samples were taken according to CTD-profiles: samples were taken from the following depth strata: 1) the upper mixed layer (UML); 2) the layer of high temperature gradients (from the upper boundary of thermocline to the depth of 8 deg C temperature); 3) cold Intermediate layer (CIL) - the layer with the T&lt; 8 deg C; 4) from the depth of sigma theta = 15.8 (oxycline) to the lower boundary of CIL; 5) from the depth of sigma theta = 16.2 to the depth of sigma theta = 15.8. Samples were analysed for zooplankton species and stage composition and abundance.Juday net: Vertical tows of a closing Juday net, with mouth area 0.1 m**2, mesh size 180µm. Samples were taken from different layers. Towing speed: 1m/s. Samples were preserved by a 4% formaldehyde sea water buffered solution. Sampling volume was estimated by multiplying the mouth area by the wire length.The entire sample or an aliquot (1/2 to1/4) was analyzed under the binocular microscope. Mesozooplankton species and stages were identified and enumerated; meroplankton were identified and enumerated at higher taxonomic level. Taxonomic identification was done at Shirshov Institute of Oceanology using the relevant taxonomic literature (Rose, 1933, Brodsky, 1950, and Internet resources).
