The M  7.4 Cape St. James earthquake in 1970 is located in the southernmost part of the Queen Charlotte fault ( QCF ). Operational permanent seismographic stations are designated by solid...

Seafloor venting of gas and water from the gas hydrate zone ( Tryon et al., 1999 ; Taylor et al., 2000 ) and the presence of gas plumes within the gas hydrate zone ( Gorman et al., 2002 ; Pecher, 2002 ; Wood et al., 2002 ) suggest...

The occurrence of Retispora lepidophyta and Vallatisporites hystricosus , indicating...

... and the palaeoenvironment is explored from a constrained chronostratigraphic context in two technocomplexes from the southern Cape coast, the Mossel Bay from Klasies River Main site, and the Oakhurst from Klipdrift Cave. Significant changes in the shore habitat are not reflected at technocomplex level, but lithic densities...

... faunal turnover in the manner predicted by the TPH remains unclear. In this study, we test the underlying mechanics of the TPH using well-dated Quaternary ungulate records from southern Africa's Cape Floristic Region (CFR). Changes in sea level, vegetation, and topographic barriers across glacial...

... al., 2014 ). In most studies, flares have been observed as a ship passes over them. Although seafloor observations indicate that individual bubbling vents are ephemeral (e.g.,  Tryon et al., 1999 ), repeat surveys have suggested that the general locations where flares are observed may remain...

..., Hymenophyllum is, at present, a predominantly pantropical genus with a wide distribution. Hymenophyllum mecodium also occurs in boreal climates as scattered colonies in British Columbia and southern Alaska ( Tryon and Tryon, 1982 ). Schizaea is also principally a pantropical genus, but the temperate...

Interestingly, three of the sites have both diurnal and tidal signals, J33C with increased rates during the day and at high tide, FS45D with increased rates during the night and at high tide, and FS04D with increased rates at night and during low tide.

On the Kodiak shelf, the central shelf uplift and the Dangerous Cape High are aligned with the Kodiak-Bowie basement ridge ( Fisher and von Huene, 1980 ). Onshore are 4 terraces locally uplifted 3–5 times more rapidly than terraces at other parts...

Such processes are all directly impacted by the transport of mass...
