![]() Sieber and his colleagues lift the veil on some of the mechanisms that control the behavior of zinc in the Pacific Ocean, and more globally. It compares the results of several popular formulas. The North Pacific Ocean, a key actor for the zinc oceanic cycle This free lean body mass (LBM) calculator estimates LBM based on body weight, height, age, and gender. Journal of Geophysical Research: Oceans, 127(9). Synoptic 129 I and CFC–SF 6 Transit Time Distribution (TTD) Sections Across the Central Arctic Ocean From the 2015 GEOTRACES Cruises. A revised glacial section of deep water 13C. Superimposed are contours of derived advection age (reconstructed from Schlosser et al. The origins of the water masses are supported by the meridional gradients in benthic foraminiferal 18O. Maps of respective tracer sections are illustrated in top panels. Figure 13 shows bottom tracer age (where water depth is at least 3300 m). ![]() Right panels: Tracer sections across Makarov and Eurasian Basin for (d) CFC-11 (e) SF 6 and (f) 129I. Figure: Left panels: Tracer sections across Canada Basin and Eurasian Basin for (a) CFC-11 (b) SF 6 and (c) 129I. The high mixing values found in the upper halocline are congruent with the nutrient maximum indicating that both are governed by winter shelf mixing processes. 8C) and contributed to increased dissolved oxygen. 4B) is reflected in the ideal age of the water masses in the western Panthalassa (Fig. Their calculated mean age sections are conform to historical ideas of tracer ages while the mixing time is nearly constant in upper intermediate water, which reflects the influence of strong advective flow. Upwelling in re- gions east of the mid-ocean ridge (Fig. The resulting large, quasi-synoptic tracer data sets provide an opportunity to use these transient tracers to determine water mass mean ages and mixing rates in a highly stratified, arctic, marine system. and one German GEOTRACES cruises that occurred in 2015 (cruises GN01 and GN04). bulloides and on the radiocarbon ages obtained from planktonic foraminifera samples. Smith and colleagues determined iodine-129 ( 129I), chlorofluorocarbons (CFC-11) and sulfur hexafluoride (SF 6), in the Arctic Ocean in samples collected during two U.S. ![]()
