title: Seawater carbonate chemistry and particulate organic and inorganic carbon, growth of Emiliania huxleyi

description: Coccolithophore responses to changes in carbonate chemistry speciation such as CO2 and H+ are highly modulated by light intensity and temperature. Here, we fit an analytical equation, accounting for simultaneous changes in carbonate chemistry speciation, light and temperature, to published and original data for Emiliania huxleyi, and compare the projections with those for Gephyrocapsa oceanica. Based on our analysis, the two most common bloom-forming species in present-day coccolithophore communities appear to be adapted for a similar fundamental light niche but slightly different ones for temperature and CO2, with E. huxleyi having a tolerance to lower temperatures and higher CO2 levels than G. oceanica. Based on growth rates, a dominance of E. huxleyi over G. oceanica is projected below temperatures of 22 °C at current atmospheric CO2 levels. This is similar to a global surface sediment compilation of E. huxleyi and G. oceanica coccolith abundances suggesting temperature-dependent dominance shifts. For a future Representative Concentration Pathway (RCP) 8.5 climate change scenario (1000 µatm fCO2), we project a CO2 driven niche contraction for G. oceanica to regions of even higher temperatures. However, the greater sensitivity of G. oceanica to increasing CO2 is partially mitigated by increasing temperatures. Finally, we compare satellite-derived particulate inorganic carbon estimates in the surface ocean with a recently proposed metric for potential coccolithophore success on the community level, i.e. the temperature-, light- and carbonate-chemistry-dependent CaCO3 production potential (CCPP). Based on E. huxleyi alone, as there was interestingly a better correlation than when in combination with G. oceanica, and excluding the Antarctic province from the analysis, we found a good correlation between CCPP and satellite-derived particulate inorganic carbon (PIC) with an R2 of 0.73, p &lt; 0.01 and a slope of 1.03 for austral winter/boreal summer and an R2 of 0.85, p &lt; 0.01 and a slope of 0.32 for austral summer/boreal winter.

title: Whale sightings during POLARSTERN cruise PS113 (ANT-XXXIII/4)

description: Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS113 (Punta Arenas - Bremerhaven) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken if possible for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.
description: Date/Time is given in UTC. Certainty of identification: definite if observer clearly identified the species. The number of individuals is binned according to the options given in the data acquisition software: 1, 2, 3, less equal 5, less equal 10, greater than 10, greater than 20. More precise values may exist, due to observer comments.

title: Substrate-inhibitor test with E. huxleyi

description: Carbonate chemistry and calcification data of the substrate-inhibitor interaction experiment with E. huxleyi. The percentage of 200 cells possessing/producing coccoliths was investigated by means of cross-polarized light microscopy which allows detection of internal coccoliths. These birefringence measurements were backed up with scanning electron microscopy (SEM) investigations when the presence of coccoliths could not be unequivocally determined. In case of discrepancies among the two methods, we relied on SEM investigations since this is the most reliable approach.

title: Seawater carbonate chemistry and physiological performance parameters of Carcinus maenas under respective incubation conditions

description: Ocean acidification causes an accumulation of CO2 in marine organisms and leads to shifts in acid-base parameters. Acid-base regulation in gill breathers involves a net increase of internal bicarbonate levels through transmembrane ion exchange with the surrounding water. Successful maintenance of body fluid pH depends on the functional capacity of ion-exchange mechanisms and associated energy budget. For a detailed understanding of the dependence of acid-base regulation on water parameters, we investigated the physiological responses of the shore crab Carcinus maenas to 4 weeks of ocean acidification [OA, P(CO2)w = 1800 µatm], at variable water bicarbonate levels, paralleled by changes in water pH. Cardiovascular performance was determined together with extra-(pHe) and intracellular pH (pHi), oxygen consumption, haemolymph CO2 parameters, and ion composition. High water P(CO2) caused haemolymph P(CO2) to rise, but pHe and pHi remained constant due to increased haemolymph and cellular [HCO3-]. This process was effective even under reduced seawater pH and bicarbonate concentrations. While extracellular cation concentrations increased throughout, anion levels remained constant or decreased. Despite similar levels of haemolymph pH and ion concentrations under OA, metabolic rates, and haemolymph flow were significantly depressed by 40 and 30%, respectively, when OA was combined with reduced seawater [HCO3-] and pH. Our findings suggest an influence of water bicarbonate levels on metabolic rates as well as on correlations between blood flow and pHe. This previously unknown phenomenon should direct attention to pathways of acid-base regulation and their potential feedback on whole-animal energy demand, in relation with changing seawater carbonate parameters.

title: GISP2 14-C (radiocarbon) measurements (Table 1)

description: Approx age of ice based on layer counting and delta 18O data for trapped air (Grootes et al., 1993; Sowers et al., 1993; Meese et al., 1994a; Stuiver et al., 1995). Typical errors in determination of 14C concentration in recent samples are 50-60 atoms/g, which includes statistical errors and uncertainties. The larger errors arise from multiple extractions, and in samples from depths 100.4 to 1518 from 14C-decay corrections.

title: GISP2 14-C (radiocarbon) measurements (Table 2)

description: Expected in-situ 14C is based on 14C production rate at surface for the present altitude (3.2 km), 200 atoms 14C/g ice/y (Jull et al., 1994), and model ice accumulation rates estimated by Cutler et al. (1995). The estimates are in-situ cosmogenic 14C (i.e. excluding trapped 14C). For total - trapped CO2, the amount of trapped 14CO2 is estimated from the amount of air in the ice (tab1) and assuming 250 ppm CO2 in air.

title: Estimating the effects of student houselessness on learning outcomes and exploring for variation

description: Houselessness affects over a million US students annually. Previous scholarship has detailed the experiences of unhoused students, as well as some steps schools can take to better support them. Still, little is known about the impacts of houselessness on learning outcomes, or the ways in which locale, different temporary housing accommodations, and race/ethnicity may complicate this relationship. Using data from the U.S. Department of Education (ED), the Stanford Education Data Archive (SEDA), and the Research Alliance for New York City Schools (RANYCS), this dissertation quantitatively explores the relationship between student houselessness and learning outcomes, and explores potential sources of variation in the magnitude of this relationship. Analyses include descriptive statistics and multi-variate linear regression models. This dissertation consists of two studies: the first is a national study, with analyses conducted at the district level, and the second is student level study in New York City (NYC). Results from Study #1 demonstrate a statistically significant relationship between rates of student houselessness and average standardized test performance at the district level. Furthermore, they demonstrate significant variation in the magnitude of this relationship across different levels of district urbanicity. Results from Study #2 in NYC confirm that houselessness is significantly associated with student’s learning outcomes at the individual level. They also demonstrate significant variation in the magnitude of this relationship across students’ temporary housing accommodations and racial/ethnic groups. Lastly, I find that student houselessness in NYC is also associated with the number of Office Disciplinary Referrals that a student receives and a student's likelihood of being chronically absent.

title: Oxygen fluxes of coral Xenia umbellata in a aquarium experiment

description: One coral colony per tank was used for oxygen flux measurements, with incubations conducted every 7 days (n = 3 per treatment). On measurement days, oxygen fluxes were assessed 1 hour after organic C treatment using a beaker incubation technique. Corals were placed in 160 ml glass beakers filled with tank water, sealed underwater, and incubated in a thermostat-controlled (~25°C) water bath with stirring (190 rpm). Incubations lasted 1.5 h in light (~100 µmol photons m⁻² s⁻¹ PAR) and 1.5 h in dark, with oxygen concentrations recorded before and after using an optode sensor. Xenia umbellata originates from the Red Sea.
