IAEA’97 expedition to the NW Pacific Ocean—results of oceanographic and radionuclide investigations of the water column

Spatial distribution of 3H, 90Sr, 137Cs and 239,240Pu in surface waters of the Pacific and Indian Oceans—GLOMARD database

“…7-10 for the years 1996-2000. Here, the data are very sparse and are mainly based only on the results obtained in the framework of the WOMARS project (Povinec et al, 2003a). A comparison (where possible) of decay-corrected data shows more or less the same trend in data observed for the years 1991-1995.…”

The 129-iodine content of subtropical Pacific waters: impact of Fukushima and other anthropogenic 129-iodine sources

“…We compare our results with data from the IAEA-97 radiochemistry cruise (Povinec et al, 2003) and individual profiles to the northeast of Japan (Suzuki et al, 2010(Suzuki et al, , 2013. One of the IAEA-97 stations is from within the climatological mean of the Kuroshio near the northwest edge of the North Pacific subtropical gyre (NPSG), one station from just within the western NPSG, and two near the Marshall Islands from within the North Equatorial Current.…”

“…To estimate this possible perturbation to the North Pacific pre-anthropogenic 129 I budget, we simplify the region contained by stations 2, 3, 6, and 7 (Povinec et al, 2003(Povinec et al, , 2010 to a triangle with an area in excess of 2.4 × 10 6 km 2 . We fit a smoothed polynomial to the merged 129 I data presented in Fig.…”

Vertical distributions of226Ra,228Ra, and137Cs activities in the southwestern part of the Sea of Okhotsk

“…1e). Differing the gradients from surface or subsurface in other oceans Povinec et al, 2003), the activity of fallout 137 Cs in the SY09C waters exhibits small variation in ICW (∼ 1 mBq l −1 ), remaining similar to the surface level, and it continues to decrease in TLW and the deep layer water (0.5 to 0.1 mBq l −1 ) ( fig. 1f).…”
