During the Polarstern cruise PS131 photos of the surface (open ocean and sea ice) were recorded from onboard the vessel with a down-looking camera (GoPro Hero 9 Black) that was...

Manganese nodules from VA13/2 cruise (R/V Valdivia) were selected for a variety of morphologies and size. They were regrouped by size class and chemically analyzed in bulk. Mn,...

The manganese content of 4 manganese nodules was determined by atomic absorption. The decrease of total alpha activity was used to evaluate Mn accumulation. Because CaCO3 is a...

The manganese content of 7 manganese nodules was determined by neutron activation. The decrease of unsupported 231Pa and 230Th in the outer few tenths of millimeters was used to...

For a pelagic sediment core taken in the Atlantic Ocean, The decrease of unsupported 231Pa was used for the determination of the accretion rate. Because CaCO3 is a Mn-free...

For 4 pelagic sediment cores taken in the Atlantic Ocean, Ericson's paleontologic boundaries X-Y (75 000 yr) and Y-Z (11 000 yr) were used. The age of the upper boundary was...

For 7 pelagic sediment cores, the decrease in unsupported 130Th activity with depth in the core was used to establish the mean accumulation rate over the last 300 000 years....

For 27 pelagic sediment cores, the Brunnes-Matuyama magnetic reversal boundary (700 000 yr) was used to establish the mean sedimentation rate between this level and the core...

Mn crust samples were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line Islands Archipelago between 15°S and...

Ten large (surface area = 50-360 cm 2) manganese nodules and crusts from the Pacific, Atlantic and the Indian Oceanshave been selected for ¹⁰Be and ⁹Be isotopes evaluation....

During a short geological cruise in May 1979 by HMAS Kimbla, two manganese nodules were recovered from the deep sea about 250 nautical miles southeast of Sydney. They were...

The authors have selected for analysis a manganese nodule from Station 20 of the PLEIADES Mn7601 campaign. This "apple" shaped nodule (6.5x3.0 cm) was laying on a bed of...

Using radiochemical methods, the authors have measured the distribution of uranium, thorium, radium, polonium and protactinium isotopes from the top and bottom sides of the a...

The samples were collected from R/V "Yaquina" at 13°40'S, 102°8'W during cruise YALOC-73 of Oregon State University. The Mn nodules were sorted by morphological type before...

The samples analysed were dredged on Pleiades Leg II during a program of heat flow measurements, bottom photography and coring. They are located on topographic mounds in a band...
