title: Protein synthesis rates derived from incorporation of non-radioactively labeled phenylalanine in Antarctic fish

description: Temperature dependent growth is an important indicator to understand the thermal tolerance of organisms and to project their vulnerability to future climate change. Direct measurements of temperature dependent weight gains, however, are experimentally challenging and time consuming in long-lived species. Here, we reassess methodology to quantify the in vivo protein synthesis rate from amino acids, as a key component of growth. We developed an analytical method that is both robust against analytical errors and does not require hazardous radioactive materials. We utilized the incorporation of isotopically 13C15N-labeled-phenylalanine into fish muscle followed by quantification by liquid chromatography mass spectrometry to calculate accurate net protein synthesis rates in muscle tissue of Antarctic fish, Pachycara brachycephalum, in vivo. Specifically, we injected 150 mM of 13C9H915N1 phenylalanine intraperitoneally and sampled muscle tissue in 1,5h steps between 0 and 6 hours after injection. We quantified labeled and unlabeled phenylalanine both in muscle protein and in the cytosol. This allowed us to critically re-evaluate three different protein synthesis rate (Ks) calculation methodologies that have been developed over the last decades. The calculated values differ by more than 70-fold (0.048 ± 0.021% day-1 up to 3.56 ± 2.16 day-1) between methods. We argue that the Ks calculation including a proportionate ratio of protein synthesis from (unlabeled) free amino acids yields the most realistic Ks values for cold water fish. Eventually, the standardization of the net protein synthesis rate calculation will lead to dependable quantitative representations of organismal stress in response to climate change.

title: HRLT: A high-resolution (1 day, 1 km) and long-term (1961–2019) gridded dataset for temperature and precipitation across China

description: Accurate long-term temperature and precipitation estimates at high spatial and temporal resolutions are vital for a wide variety of climatological studies. We have produced a new, publicly available, daily, gridded maximum temperature, minimum temperature, and precipitation dataset for China with a high spatial resolution of 1 km and over a long-term period (1961 to 2019). It has been named the HRLT. The daily gridded data were interpolated using comprehensive statistical analyses, which included machine learning, the generalized additive model, and thin plate splines. It is based on the 0.5° × 0.5° grid dataset from the China Meteorological Administration, together with covariates for elevation, aspect, slope, topographic wetness index, latitude, and longitude. The accuracy of the HRLT daily dataset was assessed using observation data from meteorological stations. The maximum and minimum temperature estimates were more accurate than the precipitation estimates. For maximum temperature, the mean absolute error (MAE), root mean square error (RMSE), Pearson's correlation coefficient (Cor), coefficient of determination after adjustment (R²), and Nash-Sutcliffe modeling efficiency (NSE) were 1.07 °C, 1.62 °C 0.99, 0.98, and 0.98, respectively. For minimum temperature, the MAE, RMSE, Cor, R², and NSE were 1.08°C, 1.53 °C, 0.99, 0.99, and 0.99, respectively. For precipitation, the MAE, RMSE, Cor, R², and NSE were 1.30 mm, 4.78 mm, 0.84, 0.71, and 0.70, respectively. The accuracy of the HRLT was compared to those of the other three existing datasets and its accuracy was either greater than the others, especially for precipitation, or comparable in accuracy, but with higher spatial resolution and over a longer time period. In summary, the HRLT dataset, which has a high spatial resolution, covers a longer period of time and has reliable accuracy, is suitable for future environmental analyses, especially the effects of extreme weather.
description: The datasets are stored in NetCDF format. For example, the file name is China_1km_keyword_year.nc,where keyword is variable (maxtmp for maximum temperature, mintmp for minimum temperature, and prep for precipitation).The files in this dataset can be opened and viewed with the HDFView program, and the netCDF4 module in Python can read and output data.

title: Raw abundances of epigaeic arthropods on Mount Kilimanjaro

description: There are several data sets originating from the same pitfall trap samples. The other data set I just submitted contains mean abundances per plot. This data set now contains raw data at trap level (several traps per plot). I am planning to upload more data sets on specific taxa (spiders, springtails, beetles), and my colleagues should upload some more data sets on snails, millipedes and more springtails containing (but not limited to) specimen caught in the same pitfall trap samples. Abstract We sampled arthropod assemblages in disturbed and undisturbed vegetation types along an elevational gradient of 860–4550 m asl on the southern slopes of Mt. Kilimanjaro, Tanzania. On each site, ten pitfall traps were evenly spaced along two 50 m transects, with a distance of 10 m between individual traps and 20 m between transects. Pitfall traps were filled with 100–200 ml of a mixture of ethylene glycol and water (1:1 vol/vol) with a drop of liquid soap to break surface tension. Traps were exposed for 7 days each during two to five sampling events in both the dry and wet seasons between May 2011 and October 2012. As the number of individuals collected in ten traps was very high, we had to confine the sorting and subsequent analysis to sub-sets of at least three traps per sampling site and sampling event. Unfortunately, we had to find out later that the ethylen glycol procured locally was actually a mixture of ethylen glycol and 2-ethoxyethanol, which is a strong oxidizing chemical. Therefore, any sequencing of specimen caught in pitfall traps was impossible.

title: Long-term, high-resolution foraminiferal geochemical records (δ¹⁸O, δ¹³C) from IODP Site 359-U1467

description: Due to their large heat and moisture storage capabilities, the tropics are fundamental in modulating both regional and global climate. Furthermore, their thermal response during past extreme warming periods, such as super interglacials, is not fully resolved. In this regard, we present high-resolution (analytical) foraminiferal geochemical (δ^18^O and Mg/Ca) records for the last 1800 kyr from the shallow (487 m) Inner Sea drift deposits of the Maldives archipelago in the equatorial Indian Ocean. Considering the diagenetic susceptibility of these proxies, in carbonate-rich environments, we assess the integrity of a suite of commonly used planktonic and benthic foraminifera geochemical datasets (Globigerinoides ruber (white), Globigerinita glutinata (with bulla), Pulleniatina obliquiloculata (with cortex) and Cibicides mabahethi) and their use for future paleoceanographic reconstructions.Using a combination of spot Secondary Ion Mass Spectrometer, Electron Probe Micro-Analyzer and Scanning Electron Microscope image data, it is evident that authigenic overgrowths are present on both the external and internal test (shell) surfaces, yet the degree down-core as well as the associated bias is shown to be variable across the investigated species and proxies. Given the elevated authigenic overgrowth Mg/Ca (∼12–22 mmol/mol) and δ^18^O values (closer to the benthic isotopic compositions) the whole-test planktonic G. ruber (w) geochemical records are notably impacted beyond ∼627.4 ka (24.7 mcd). Yet, considering the setting (i.e. bottom water location) for overgrowth formation, the benthic foraminifera δ^18^O record is markedly less impacted with only minor diagenetic bias beyond ∼790.0 ka (28.7 mcd). Even though only the top of the G. ruber (w) and C. mabahethi records (whole-test data) would be suitable for paleo-reconstructions of absolute values (i.e. sea surface temperature, salinity, seawater δ^18^O), the long-term cycles, while dampened, appear to be preserved. Furthermore, planktonic species with thicker-tests (i.e. P. obliquiloculata (w/c)) might be better suited, in comparison to thinner-test counter-parts (i.e. G. glutinata (w/b), G. ruber (w)), for traditional whole-test geochemical studies in shallow, carbonate-rich environments. A thicker test equates to a smaller overall bias from the authigenic overgrowth. Overall, if the diagenetic impact is constrained, as done in this study, these types of diagenetically altered geochemical records can still significantly contribute to studies relating to past tropical seawater temperatures, latitudinal scale ocean current shifts and South Asian Monsoon dynamics.

title: Diffusive oxygen uptake from the Laptev Sea (Arctic Ocean) during POLARSTERN cruise ARK-XXVII/3 (IceArc) from August-September 2012

description: In this study, we measured a range of biogeochemical parameters down the Laptev Sea continental slope, from around 50 to 3400 m water depth. These included chlorophyll pigments, extracellular enzymatic activity, diffusive oxygen uptake and prokaryotic cell abundance. Our aim was to compare the measurements between two years about two decades apart (1993 and 2012).Benthic oxygen consumption rates were determined from ex situ microsensor measurements of diffusive oxygen uptake in retrieved sediment cores, consistent with Boetius & Damm 1998 (doi:10.1016/S0967-0637(97)00052-6). Directly after recovery, cores were stored at in situ temperature and the overlying water gently stirred by rotating small magnets to avoid the development of a stagnate water body above the sediment. High-resolution microprofiles across the sediment water interface were measured using Clark-type O2 microelectrodes equipped with a guard cathode (Revsbach 1989 doi:10.4319/lo.1989.34.2.0474) mounted to motorized micromanipulator (Glud et al. 2009 doi:10.4319/lo.2009.54.1.0001). Sensors were calibrated at in situ temperature against (1) air-saturated bottom water taken from the overlying water from the MUC cores (100% saturation), and (2) dithionate-spiked bottom water (anoxic). Microprofiles across the sediment-water interface were measured with a vertical resolution of 100 μm on a total length of max. 5 cm. The diffusive oxygen uptake (DOU, mmol/m²/d¹) was calculated from the O2 gradient just below the sediment surface and Fick's first law of diffusion (Rasmussen and Jorgensen 1992 doi:10.3354/MEPS081289).DOU = por * Ds * δC/δzwhere Ds (cm⁻² s⁻¹) = molecular diffusion coefficient in sediment, calculated as Ds = D0 * por/m , where por is the porosity, D0 = diffusion coefficient in water and m = 3, C (μM) = solute concentration, z (cm) = depth in the sediment.Carbon flux (remineralization rates, mg C/m²/d) were calculated from oxygen uptake at the seafloor assuming a molar ratio of C = 0.77 O2 as in Boetius & Damm 1998 (doi:10.1016/S0967-0637(97)00052-6).

title: Summer hydrophysical properties of thermokarst lakes in the Central Yakutian Lowland and mountain lakes in the Verkhoyansk Mountain Range in Eastern Yakutia

description: This dataset presents the assessment of the lake types and settings together with the data on hydrophysical parameters measurements including Electrical Conductivity, on-site water temperature and pH, except at one lake (EN21426-2) of which electrical conductivity was measured in the Hydrochemical Laboratory of AWI). Lakes were surveyed between 6 August and 2 September 2021. A total of 66 lakes in Central and Eastern Yakutia were assessed as part of the joint Russian-German expedition (NEFU-AWI; RU-Land_2021_Yakutia). Of those 66 lakes, 15 are from mountain lakes located within the Verkhoyansk mountain range, at the eastern end of the expedition route, including mostly intermontane basin or glacial lakes (average elevation: c. 1080 m a.s.l.). 13 lakes were sampled in Oymyakonsky District and two lakes in Tomponsky District. The hydrochemical dataset from the other 52 lakes that lie within the eastern extent of the Central Yakutian Lowland (average elevation: c. 190 m a.s.l.) represents thermokarst lakes. Thermokarst lakes originate from thawing of ice-rich permafrost and were found in different stages of their development, with a wide range of anthropogenic impact. These 52 thermokarst lakes include seven lakes within the Churapchinsky District, two are located in the Tattinsky District further east within a freshly burned forest. 42 lakes are located in Megino-Kangalassky District, of which 17 lakes are around Tungulu, and 24 lakes around Maya settlements.

description: During the Maria S. Merian cruise MSM95 to the Fram Strait in 2020, water samples were collected from nine stations using a CTD rosette sampler (SeaBird SBE 911Plus). Samples were collected at several depths. From each sample, 4 L of seawater was filtered onto a 0.7 µm GF/F filter using a peristaltic pump. The filters were immediately stored at -80 °C. From each of the filters, 2 x 11.2 mm circular pieces were removed and subject to acid hydrolysis (1 M HCI for 24 h at 100 °C). The aliquots were run in a speed vac before resuspension in MilliQ. Measurements of monosaccharides were obtained using High-performance anion exchange chromatography with pulsed amperometric detection along with standards.
