Annotated record of the detailed examination of Mn deposits from R/V Atlantis - Cruise 151 (Dec. 1947) in the Atlantic Ocean

One of the objectives of WHOI Atlantis Cruise 151, covering the period from 7 December 1947 to 18 June 1948, was to obtain as complete a sampling of the sea bottom of the Meditterranean and Aegean Seas as was compatible with the remainder of the scientific program. It was furthermore planned to make concurrent bottom photographs as a means for studying the correlation between bottom sediments and the morphology of the sea floor. The photographs also held the possibility of determining the presence of bottom fauna. The underwater camera used for this work was loaned to us by Dr. Maurice Ewing of Columbia University. As it was fitted with a one foot long coring tube at the base of its pole a majority of the bottom samples were obtained by the camera itself. On the way to Gibraltar, several bottom photos were taken in the Atlantic ocean. One of them was the deepest underwater photograph ever taken at the tima (3026 fathoms) showing a cluster of objects, some as much as 5 inches across on a clay bottom. These appeared to be manganese nodules, judging from their rounded and bulbous shape, especially the potato-like form of some of them. A core sample obtained at the same spot with a corer attached to the camera stand contained abundant manganese grains.

Biomarker proxies on ODP Holes 151-912A and 151-912B

A novel and promising biomarker proxy for reconstruction of Arctic sea ice conditions was developed and is based on the determination of a highly branched isoprenoid with 25 carbons (IP25). IP25 records have been restricted to the last 150 kyr BP. We present a biomarker record from Ocean Drilling Program (ODP) Site 912, going back to the Pliocene-Pleistocene boundary and indicating that sea ice of variable extent occurred in the Fram Strait/southern Yermak Plateau area at least since about 2.2 Ma. Furthermore, our data support the idea that a combination of IP25 and open water, phytoplankton biomarker data ("PIP25 index") may give a more reliable and quantitative estimate of past sea ice cover (at least for the study area). The study reveals that the novel IP25/PIP25 biomarker approach has potential for semi-quantitative paleo-sea ice studies covering the entire Quaternary and could motivate further detailed high resolution research on ODP/IODP material using this proxy.

Total organic carbon (TOC) on ground bulk and carbonate-free sediment samples of ODP Hole 151-911A

A multiproxy analysis of Hole 911A (Ocean Drilling Program (ODP) Leg 151) drilled on the Yermak Plateau (eastern Arctic Ocean) is used to investigate the behaviour of the Svalbard/Barents Sea ice sheet (SBIS) during late Pliocene and early Pleistocene (~3.0-1.7 Ma) climate changes. Contemporary with the 'Mid-Pliocene (~3 Ma) global warmth' (MPGW), a warmer period lasting ~300 kyr with seasonally ice-free conditions in the marginal eastern Arctic Ocean is assumed to be an important regional moisture source, and possibly one decisive trigger for intensification of the Northern Hemisphere glaciation in the Svalbard/Barents Sea area at ~2.7 Ma. An abrupt pulse of ice-rafted debris (IRD) to the Yermak Plateau at ~2.7 Ma reflects distinct melting of sediment-laden icebergs derived from the SBIS and may indicate the protruding advance of the ice sheet onto the outer shelf. Spectral analysis of the total organic carbon (TOC) record being predominantly of terrigenous/fossil-reworked origin indicates SBIS and possibly Scandinavian Ice Sheet response to incoming solar radiation at obliquity and precession periodicities. The strong variance in frequencies near the 41 kyr obliquity cycle between 2.7 and 1.7 Ma indicates, for the first time in the Arctic Ocean, a close relationship of SBIS growth and decay patterns to the Earth's orbital obliquity amplitudes, which dominated global ice volume variations during late Pliocene/early Pleistocene climate changes.
