The Larsen C Ice Shelf (LCIS) is the largest ice shelf in Antarctica Peninsula, and its state can be considered to an indicator of local climate change. goal this paper invert rigidity LCIS based on interferometric synthetic aperture radar (InSAR) technique using Sentinel-1 images. A targeted processing chain first used obtain reliable phase measurements under circumstance rapid flow. Unfortuna...

Lithostratigraphy, depositional facies architecture, and diagenesis of upper Pliocene to Holocene carbonates in northern Belize are evaluated based on a ca 290 m, continuous section of samples from a well drilled on Ambergris Caye that can be linked directly to outcrops of Pleistocene limestone, and of overlying Holocene sediments. Upper Pliocene outer-ramp deposits are overlain unconformably b...

The ocean bottom morphology, depth, sediment grain size, sorting, carbonate content, and water depth are used to compose seafloor maps as support for biological studies. Sediments reworked by waves currents accumulate according the hydrodynamic level on continental shelf. In contrast, sediments accumulated pelagic settling, mass wasting, turbidity flows, boundary slope. Sea oscillations during ...

The July 2020 Mw 7.8 Shumagin earthquake occurred in the seismic gap region along Aleutian subduction zone. This interplate generated a small tsunami, but with unusual long-period waves ranging between 40 and 90 min. We examined cause of such an anomalous ocean wave through source modeling inverted from tsunami geodetic data. Our model indicates that plate-boundary rupture area was confined at ...

In order to analyze the main factors controlling shale gas accumulation and predict potential zone for exploration, heterogeneous characteristics of source rock reservoir Wufeng-Longmaxi Formation in Sichuan Basin were discussed detail, based on data petrology, sedimentology, physical properties content. On this basis, effect coupling between generation reservation has been analyzed. The black ...

The genus Phaeocystis is distributed globally and has considerable ecological, biogeochemical, societal impacts. Understanding its distribution, growth ecological impacts been limited by lack of extensive observations on appropriate scales. In 2018, we investigated the biological dynamics New England continental shelf encountered a substantial bloom pouchetii. Based satellite imagery during Jan...
