4. The seawater composition has been resulted by both submarine weathering and hydrothermal alteration of komatiitic crust. It was very similar to the modern seawater, but dissolved CO2, silica and iron were more abundant.We thank Dr. M.V. Mironenko (Vernadsky Institute) for the modeling code...
Briefly, we prepared sediment samples by centrifuging each one for 30 min at 4400 rpm and 4 ºC; the membrane filter (seawater sample) and sponge samples were each cut into small pieces. The whole membrane filter and 500 mg of sediment and sponge were transferred to Lysing Matrix E ...
We found diverse, species-specific microbiomes, distinct from the surrounding seawater. Microbiomes were comprised of few abundant bacteria, which constituted the majority of sequences (up to 58% depending on the coral species). In addition, we found a high diversity of rare bacteria (taxa at ...

δD and δ18O in water samples were determined using a liquid water isotope analyzer LWIA-45-EP, with an accuracy level of 0.1 ‰ and 0.3 ‰, respectively. The measurement results are expressed using the thousand difference [δ (‰)] of the Vienna standard average seawater (VSMOW)....
We also report the Os isotopic compositions of umber samples collected from the Aki area and discuss the seawater Os isotopic composition of the Middle to Late Cretaceous Pacific Ocean. The Aki umber deposit is located in the Northern Shimanto Belt, central Shikoku, southwest Japan (Fig. 1). ...

Seawater samples were collected in surface during Leg 1b and at different depths during Leg 2b (Figure 1). Ancillary data of temperature, salinity, chlorophyll and nitrate con- centration were kindly provided by JE Tremblay and J Gagnon (Table 1). Seawater was collected with a bucket (Leg 1...
Mixture: 10 weight parts highly calcined seawater magnesite composed of 95 weight percent MgO, approximately 2 weight percent CaO, 2 weight percent SiO2and 1 weight percent Fe2O3, 30 weight parts of Bayer alumina containing 0.3 weight percent of Na2O, 48 weight parts of quartz sand containing ...
