Low resolution Mg/Ca on planktonic foraminiferal calcite from MD96-2048 (Pleistocene) - T. sacculifer
No full textThis study was conducted to evaluate discrepancies between SST proxies and to assess their sensitivity to oceanographic changes. These data contribute to improved proxy interpretation, particularly for paleoceanographic reconstructions in subtropical ocean settings. This dataset provides sea surface temperature (SST) reconstructions over the past 1.25 million years from sediment core MD96-2048, collected at 660 m water depth near Delagoa Bight in the southwestern Indian Ocean (26°10.482′S, 34°01.148′E) during the Marion Dufresne MD104 cruise. The dataset includes Mg/Ca ratios geochemical records from planktonic foraminifera, presented at low resolutions (10 datapoints). Mg/Ca analyses were conducted on Trilobatus sacculifer (new data presented here), and compared with Mg/Ca on Globigerinoides ruber (published by Caley et al., 2011; doi:10.5194/cp-7-1285-2011) using inductively coupled plasma optical emission spectrometry (ICP-OES). Clumped isotope measurements were performed on G. ruber and are available in the EarthChem dataset. The age model is based on benthic foraminiferal δ¹⁸O stratigraphy from the same core (Caley et al., 2011, doi:10.5194/cp-7-1285-2011). The dataset spans the Quaternary period, with temporal coverage from 0 to 1.25 million years before present. Sampling resolution for Mg/Ca of T. sacculifer is very low (10 datapoints over the last 1.25 Ma), allowing for investigation of differences between Mg/Ca and clumped isotopes.
SSTs were primarily calculated using the T. sacculifer Mg/Ca–temperature calibration from Anand et al. (2003, doi:10.1029/2002PA000846), applying the equation with the constant A assumed for this morphotype (with sac). To account for salinity-related biases in Mg/Ca, calibration adjustments based on Gray and Evans (2019, doi:10.1029/2018PA003517) were also incorporated. Data are provided as tabulated time series of raw geochemical measurements and calculated SST estimates

Pollen, microcharcoal and benthic foraminifera oxygen isotope data of IODP Site U1479
No full textThis study presents pollen, microcharcoal and benthic foraminifera oxygen isotope records generated from International Ocean Discovery Program (IODP) Exp. 361 Site U1479 from the Cape Basin offshore of South Africa for the period between 3.337 and 2.875 Ma. With an average sample resolution of 3 ka, this record represents the yet highest-resolution record of mPWP vegetation change from the region
Welvaert et al. Bogong moth and Common Koel surveillance
No full textThe EXCEL datasheets "Common Moth", "Common Koel 1", "Common Koel 2", Common Koel 3", "Symp Moth 1", "Symp Moth2", "Symp Koel 1", "Symp Koel 2", "Symp Koel 3", and "Symp Koel 4" are relevance summaries (0=non-relevant, 1=relevant) of de-identified tweets (from Twitter). Tweets were produced using the Commonwealth Scientific & Industrial Research Organisations Emergency Situation Awareness (ESA) system. They are derived by the searches defined within the associated manuscript. The survey data of Bogong Moth data are field data collected from the summit ridge of Mount Gingera, Brindabella Ranges, Australia.

Pollen and Spores of sediment core MD96-2048 Pleistocene
No full textTo study the influence of pCO2 on the Pleistocene development of the SE African vegetation, we used the pollen record of a marine core (MD96-2048) retrieved from Delago Bay south of the Limpopo River mouth in combination with stable isotope and geochemical proxies. Applying endmember analysis four pollen assemblages could be distinguished representing different biomes: heathland, mountain forest, shrubland and woodland. It turned out that the vegetation of the Limpopo River catchment and the coastal region of southern Mozambique is not only influenced by hydroclimate but by temperatures and atmospheric pCO2, as well. Our results suggest that the extension of either open ericaceous vegetation including C4 sedges or mountain forest depended on glacial pCO2 levels and that the main development of woodlands in the area took place after the Mid-Brunhes Event when interglacial pCO2 levels rose over 270 ppmv
Comparing two athletic recovery positions between maximum effort training intervals
No full textRecovery is an extremely important component of successful exercise and fitness both on the sports field, and throughout the life course. Fitness enthusiasts and athletes understand the importance of utilizing specific training regimes to realize optimal performance. Throughout time spent as coaches of various types and levels of sport, the authors have observed a consistent clash between common recovery positions recommended by coaches to their athletes: hands behind head (HBH), and hands on knees (HOK). As a coach or trainer, comprehension of how the body works when it comes to exercise recovery is imperative, because it allows them to tap more deeply into the athletic potential of their pupils. We will explore the functionality of HBH and HOK recovery positions using a slightly modified version of the classic Wingate Anaerobic Test (WAnT). It will incorporate a 30 second sprint followed by a 180 second HOK or HBH recovery period‚ work to rest ratio of 1:6‚ and one additional 30 second round of sprint style exercise following said recovery period.
