Benthic foraminiferal record from Santa Barbara basin

The oxygen minimum zone (OMZ) of the late Quaternary California margin experienced abrupt and dramatic changes in strength and depth in response to changes in intermediate water ventilation, ocean productivity, and climate at orbital through millennial time scales. Expansion and contraction of the OMZ is exhibited at high temporal resolution (107-126 year) by quantitative benthic foraminiferal assemblage changes in two piston cores forming a vertical profile in Santa Barbara Basin (569 m, basin floor; 481 m, near sill depth) to 34 and 24 ka, respectively. Variation in the OMZ is quantified by new benthic foraminiferal groupings and new dissolved oxygen index based on documented relations between species and water-mass oxygen concentrations. Foraminiferal-based paleoenvironmental assessments are integrated with principal component analysis, bioturbation, grain size, CaCO3, total organic carbon, and d13C to reconstruct basin oxygenation history. Fauna responded similarly between the two sites, although with somewhat different magnitude and taxonomic expression. During cool episodes (Younger Dryas and stadials), the water column was well oxygenated, most strongly near the end of the glacial episode (17-16 ka; Heinrich 1). In contrast, the OMZ was strong during warm episodes (Bølling/Allerød, interstadials, and Pre-Boreal). During the Bølling/Allerød, the OMZ shoaled to <360 m of contemporaneous sea level, its greatest vertical expansion of the last glacial cycle. Assemblages were then dominated by Bolivina tumida, reflecting high concentrations of dissolved methane in bottom waters. Short decadal intervals were so severely oxygen-depleted that no benthic foraminifera were present. The middle to late Holocene (6-0 ka) was less dysoxic than the early Holocene.

Defences of the Niagara Frontier (1764-1870) : An Historical Survey of Fort George, Fort Erie & Fort Mississauga

The intention of the Niagara Parks Commission to undertake restorations of Fort George, Fort Mississauga and Fort Erie has inspired this survey. The aim has not been to create an historical narrative - so many already exist - but rather to present an accurate description of the original appearance, structure and design of each of the Niagara Forts. This it is hoped may be of some practical assistance to those in charge of the actual work of restoration. In the case of Fort Mississauga which was maintained as a military post until 1857, vary complete information has been available. Fort George and Fort Erie were abandoned for military purposes after the War of 1812 and fewer plans and contemporary accounts have survived. While the work of research, involving the collection of every possible plan of the works and every drawing of their appearance as well as the piecing together of material, has been more difficult in the case of the latter forts, it is felt that the essential information has been secured. The use of a number of military terms in the description of the fortifications has been unavoidable and a glossary of these is included on page 66. The list of plans and illustrations is as complete as possible.
