    Zinc and Phytate Distribution in Peas. Influence of Heat Treatment, Germination, pH, Substrate, and Phosphorus on Pea Phytate and Phytase (1985)

    Notes: The largest proportions of zinc and phytate, 88.7 and 97.1%, respectively, were in the Garfield pea cotyledon; the greatest concentrations were in the germ. Cooking peas by two different methods resulted in 13% phytate reduction. Peas incubated 6.5 hr from 25 to 80°C yielded maximum phytate loss (25%) at 60°C due to phytase activated hydrolysis. Germination (10 d) decreased pea phytate 75% and increased phytase activity 12-fold. Semi-purified germinated pea phytase showed temperature optimum at 45°C, pH optimum of 5.2, 30% inhibition by 1 mM inorganic P, and substrate preference for pyrophosphate. Incubation of early germinated peas at optima pH and temperature is suggested for maximum phytate reduction.

    Effects of Germination and Dietary Calcium on Zinc Bioavailability from Peas (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 49 (1984), S. 0

    Notes: Bioavailability of zinc was determined by rat weight gain and tibia Zn response from whole pea sprouts (WPS), heat treated peas (HTP) and purified diets (PD1 and 2) supplemented with Zn and phytate for similar phytate/Zn molar ratios (phy/Zn). With diets adequate Ca (0.75%), weight gains from WPS (phy/Zn = 24) and HTP (phy/Zn = 39) were equivalent or better to a nonphytate control (NPC). Tibia Zn decreased in order from: NPC, WPS, PD1, HTP and PD2. At the 1.5% Ca level reduced growth responses from WPS and HTP indicated interaction between Ca and phytate. Zn availability from peas may be superior to that from grains and other legumes previously reported. The decreased phytate and increased phytase resulting from germination may explain the enhanced responses from pea sprouts.

    Observed Flow Compensation Associated with the MOC at 26.5 N in the Atlantic (2007)
    American Association for the Advancement of Science (AAAS)
    In:  Science, 317 (5840). pp. 938-941.

    Description: The Atlantic meridional overturning circulation (MOC), which provides one-quarter of the global meridional heat transport, is composed of a number of separate flow components. How changes in the strength of each of those components may affect that of the others has been unclear because of a lack of adequate data. We continuously observed the MOC at 26.5°N for 1 year using end-point measurements of density, bottom pressure, and ocean currents; cable measurements across the Straits of Florida; and wind stress. The different transport components largely compensate for each other, thus confirming the validity of our monitoring approach. The MOC varied over the period of observation by ±5.7 × 106 cubic meters per second, with density-inferred and wind-driven transports contributing equally to it. We find evidence for depth-independent compensation for the wind-driven surface flow.

    Temporal Variability of the Atlantic Meridional Overturning Circulation at 26.5 N (2007)

    Description: The vigor of Atlantic meridional overturning circulation (MOC) is thought to be vulnerable to global warming, but its short-term temporal variability is unknown so changes inferred from sparse observations on the decadal time scale of recent climate change are uncertain. We combine continuous measurements of the MOC (beginning in 2004) using the purposefully designed transatlantic Rapid Climate Change array of moored instruments deployed along 26.5°N, with time series of Gulf Stream transport and surface-layer Ekman transport to quantify its intra-annual variability. The year-long average overturning is 18.7 ± 5.6 sverdrups (Sv) (range: 4.0 to 34.9 Sv, where 1 Sv = a flow of ocean water of 106 cubic meters per second).
