title: Training 3D Spatially Embedded Neural Networks for Regression via Gradient Descent

description: This study examines a feed-forward neural network embedded in Euclidean R3 space. Nuclei coordinates condition network parameters. Backpropagating from loss-parameter to loss-coordinate derivatives enables spatially-embedded gradient descent. A dense multi-layer perceptron (MLP) learns price-prediction on the California Housing dataset. The model demonstrates performance comparable to conventional, non-spatial MLP predictions. Robustness examinations via re-initialisation sensitivity tests, and spatial analysis via node ablation and activation imaging, reveal complexity and interpretability characteristics unique to the spatially embedded model.

title: Elemental composition of sediment core PG2208

description: Core sections were opened alongside and cut into halves of which one was used for non-destructive XRF scanning and back-up material, while the other one was subsampled for single sample analyses. We used an AVAATECH XRF Core Scanner at AWI (Bremerhaven), equipped with Rh x-ray tube at 1.2 mA, 12 s count time for 10 kV (no filter) and 1,5 mA, 15 s count time for 30 kV (Pd filter) to scan the core in 10 mm steps for elements ranging from Al to Bi within a He atmosphere. The mean error (expressed as chi square χ2) for elements of interest was Al 2.0, Si 3.5, Ti 1.6, Mn 14.4, Fe 12.1, Br 0.6, Rb 0.7, Sr 1.0.

title: Snow depth, sea ice thickness and interface temperatures derived from measurements of SIMBA buoy 2014T33

description: The Snow and Ice Mass Balance Array (SIMBA) is a thermistor string type IMB (Jackson et al., 2013) which measures the environmental temperature SIMBA-ET and a temperature change around the thermistors after a weak heating is applied to each sensor (SIMBA-HT). SIMBA 2014T33 (a.k.a. FMI_15) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean (Polarstern PS87 (ARK28/4, ALEX) in 2014) as part of the project FMI. Its thermistor chain is 5 m long, and equipped with 240 thermistors (Maxim Integrated DS28EA00) at a spacing of 2 cm. Based on a manual classification method, the SIMBA-ET and SIMBA-HT were processed to obtain snow depth and ice thickness (smoothed with a 3-day running mean), as well as the thermistor number, the vertical position Z relative to the snow-ice interface and the measured SIMBA-ET at each detected interface (atmosphere-snow, snow-ice and ice-ocean) for the period between 2014-08-27T08:00:39 and 2015-04-08T08:00:39. To do this, we combined two derivatives of measured temperatures (the ET vertical gradient and HT rise ratio) to reduce the detection uncertainty of all interfaces considered. The snow or ice surface, consequentially the snow depth, is determined by the ET vertical gradient. Potential formation of snow ice is not explicitly considered in this data set, but may occur as depicted by vertical changes of the snow-ice interface position. The ice-ocean interface is usually determined using the HT rise ratio and serves as the lower limit for ice thickness. Overall, the accumulated error is 2 to 4 times the sensor spacing for both the snow depth and ice thickness. For interface temperatures, individual sensors in the chain measure with a temperature resolution of 0.0625°C, with the overall accuracy landing in the range of ± 2°C (Jackson et al., 2013). After the snow cover has melted, negative values for snow depth may indicate the onset of ice surface melt. Due to a malfunction of the on-board GPS unit on 02 November 2014 (12 UTC), all position values after that date are based on cleaned and smoothed (3-day running mean) position readings derived from the Iridium satellite network system.

title: Seawater carbonate chemistry, nutrients, chlorophyll and diatom Proboscia alata during experiments, 2012

description: The combined effects of different light and aqueous CO2 conditions were assessed for the Southern Ocean diatom Proboscia alata(Brightwell) Sundström in laboratory experiments. Selected culture conditions (light and CO2(aq)) were representative for the natural ranges in the modern Southern Ocean. Light conditions were 40 (low) and 240 (high) µmol photons/m**2/s. The three CO2(aq) conditions ranged from 8 to 34 µmol/kg CO2(aq) (equivalent to a pCO2 from 137 to 598 µatm, respectively). Clear morphological changes were induced by these different CO2(aq) conditions. Cells in low [CO2(aq)] formed spirals, while many cells in high [CO2(aq)] disintegrated. Cell size and volume were significantly affected by the different CO2(aq) concentrations. Increasing CO2(aq) concentrations led to an increase in particulate organic carbon concentrations per cell in the high light cultures, with exactly the opposite happening in the low light cultures. However, other parameters measured were not influenced by the range of CO2(aq) treatments. This included growth rates, chlorophyll aconcentration and photosynthetic yield (FV/FM). Different light treatments had a large effect on nutrient uptake. High light conditions caused an increased nutrient uptake rate compared to cells grown in low light conditions. Light and CO2 conditions co-determined in various ways the response of P. alata to changing environmental conditions. Overall P. alata appeared to be well adapted to the natural variability in light availability and CO2(aq) concentration of the modern Southern Ocean. Nevertheless, our results showed that P. alata is susceptible to future changes in inorganic carbon concentrations in the Southern Ocean.

title: Seawater carbonate chemistry and processes during experiments with Emiliania huxleyi, 2008

description: Ocean acidification in response to rising atmospheric CO2 partial pressures is widely expected to reduce calcification by marine organisms. From the mid-Mesozoic, coccolithophores have been major calcium carbonate producers in the world's oceans, today accounting for about a third of the total marine CaCO3 production. Here, we present laboratory evidence that calcification and net primary production in the coccolithophore species Emiliania huxleyi are significantly increased by high CO2 partial pressures. Field evidence from the deep ocean is consistent with these laboratory conclusions, indicating that over the past 220 years there has been a 40% increase in average coccolith mass. Our findings show that coccolithophores are already responding and will probably continue to respond to rising atmospheric CO2 partial pressures, which has important implications for biogeochemical modeling of future oceans and climate.
