Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]
, 2012 We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas
The Depositional Record, EarlyView.Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.

Sediment‐stressed reefs over the past 420 Myr
The Depositional Record, EarlyView.In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Physio-Géo, 2011 The western edge of Gebel Qarara (Nile Valley, Egypt) was the subject of a micro-regional geological study. After a re-reading of the lithologic stratigraphy, which corresponds to the eponymous Qarara sequence and is dated to the Middle Eocene, this ...

The Depositional Record, EarlyView.We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

Landforms Associated With the Aspect‐Controlled Exhumation of Crater‐Filling Alluvial Strata on Mars
Geophysical Research Letters, 2023 Fluvial channel belts, the deposits accumulated in rivers surrounded by floodplain deposits, are sensitive environmental recorders. Across Mars, wind has exposed ancient channel belts via the preferential erosion of floodplain strata, creating landforms ...

26Al/10Be Age of Peking Man [PDF]
, 2008 The chronological position of Peking Man, or Homo erectus pekinensis, has long been pursued, but has remained problematic due to lack of a suitable dating method^1-7^.

Carbonate sedimentology: An evolved discipline
The Depositional Record, EarlyView.Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Stop 2 Kainui silt loam and Naike clay, Gordonton Rd [PDF]
, 2008 At this stop are several remarkable features both stratigraphic and pedological, and a “two-storied” soil, the Kainui silt loam alongside (in just a few places) the Naike clay. Both soils are Ultisols. The sequence of tephra beds and buried soil horizons
