Takahashi, K., Two Year Time-series Fluxes of Silicoflagellates and Actiniscus: Size Fractioned Results from subarctic Pacific Station PAPA, – Woods Hole Oceanographic Institution Technical Report, WHOI, by: The time series sediment trap samples were collected for 4 to day periods depending on the samples; most of the samples were collected for 14 to day periods.

From a depth of m, a total of 47 samples represents a nearly two-year continuous record of the fluxes of silicoflagellate and Actiniscus : Kozo Takahashi and 孝三 高橋. In order to evaluate their value as productivity or temperature indicators, species of silicoflagellates and Actiniscus, a dinoflagellate genus with siliceous endoskeletons, were examined from the time series trap samples.

Their fluxes were enumerated for a total of samples from Station Papa and 24 samples from Station by: To study the temporal variability of oceanic productivity, time series particle fluxes were monitored at pelagic Station Papa (50°N, °W) in the eastern subarctic Pacific from September thro Cited by: Two Year Time-series Fluxes of Silicoflagellates and Actinis-cus: Size Fractioned Results from subarctic Pacific Station PAPA, – Mineral flux and biogeochemical cycles of marine.

To study the temporal variability of oceanic productivity, time series particle fluxes were monitored at pelagic Station Papa (50°N, °W) in the eastern subarctic Pacific from September through August Automated Particle Flux (PARFLUX) time series sediment traps were deployed at m and m in the m deep pelagic ocean.

The traps collected samples for 2-week periods for. Seasonal and vertical flux variations of coccolithophorids, discrete coccoliths, silicoflagellates, ebridians, and diatoms were investigated using time-series sediment traps deployed in the central Black Sea for 2 years from September through August (Year 1) and from October through September (Year 2).

Silicoflagellates Fluxes in the traps and accumulation rates in the sediment are expressed as individuals m −2 year −1. a Data are taken from Lange et al. (Lange et al., ). Yearly fluxes – Traps a × 10 8 × 10 7 × 10 8 × 10 7 × 10 8.

Fluxes of silicoflagellates, the dinoflagellate Actiniscus sp., In contrast, time-series sediment trap samples integrate production year-round (mean, g C m-2 d-l), with peak values reaching g C m-2 d- l in June-July and lower values in winter (Schemainda et al.

Micropaleontology 55(), Silicoflagellates and Actiniscus: vertical fluxes at Pacific and Atlantic sediment trap stations  Takahashi, Kozo (Woods Hole Oceanographic Institution, ) Vertical fluxes of silicoflagellate skeletons were measured in meso- and bathypelagic zones at four PARFLUX sediment trap stations located in the Pacific and Atlantic oceans.

The time series sediment trap samples were collected for 4 to day periods depending on the samples; most of the samples were collected for 14 to day periods.

From a depth of m, a total of 47 samples represents a nearly two-year continuous record of the fluxes of silicoflagellate and Actiniscus taxa. The value of N s, averaged over the depth range (5– m) for each year at all stations deeper than m and located within the geographic area bounded by –°N and –°W, increased 25% between andwith the maximum being observed in The decrease in is due to data being collected one month later than.

Polar Biology (accepted) 22 Aug A general investigation was made of the thermal expansion of various silicate fluxes The fluxes considered in the crystalline (anisotropic) and glassy (isotropic) states. were ten feldspars, two nepheline syenites, anorthosite, aplite, and lepidolite.

Benthic vegetation at the land-water interface is recognized as a filter for silica fluxes, which represents an important but under-investigated subject. This paper aims to analyze stocks and fluxes of biogenic (BSi) and dissolved (DSi) silica in relation to nitrogen (N) and phosphorus (P) in the littoral zone of a deep lake.

Specifically, we evaluated how different primary producers can.

Study Site. The sampling station (point B) is located at the entrance of the Bay of Villefranche-sur-Mer (43° N, 7° E; water depth ~85 m), on the northern coast of the Ligurian Sea, NW Mediterranean Sea (Fig.

1).It is characterized by low chlorophyll-a concentrations [], and is part of the “intermittent blooming” eco-region of the Mediterranean Sea []. Figure shows the two segmented components when the bottom-hole node is selected: reservoir and tubing components.

For a given production rate, the bottom-hole pressure can be calculated in two ways: 1) from the reservoir component using inflow equations and 2) from the tubing component using multiphase flow correlations for pipes and chokes.

In our time series, only the years with the most extreme NAO winter values (Fig. 3) reflected the hypothesis advanced by Gómez and Gorsky (Gómez and Gorsky, ): during the NAO index showed the most negative values of the record and high diatom valve fluxes were recorded, whereas during the NAO winter index exhibited its highest.

Introduction. Resolving records of global change through the most recent deglaciation event (18–11 ka) is one of the primary challenges to developing cohesive and robust theories regarding rapid climate change [].The last deglaciation was a profound event in the global climate system, wherein atmospheric [CO 2] increased by 80– ppmv [2, 3], global average temperature rose 3–4°C.
