Welland Canal Survey of Lands Hannah Secord 1828

Survey map and description of Hannah Secord's land created by The Welland Canal Company. Included is a written description of the land along with a drawing of the land. Noteable features include; line between Parnell and Secord's land, lock no.6, tow path, line between Clendenning and Secord's land. Surveyor notes are seen in pencil on the map. The deed for the land is dated February 28th, 1828. The land is located on part of lot 16 in the 6th concession of the township of Grantham. In total there are 12 acres, and 17 perches.

Stable carbon isotope in bottom water and Cibicidoides wuellerstorfi on the Ontong Java Plateau and Emperor Seamount

We have measured the carbon isotopic composition of dissolved inorganic carbon in bottom waters of the Ontong Java Plateau (western equatorial Pacific) and on the northern Emperor Seamounts (northwest Pacific). Each of these locations is several hundred miles from the nearest Geochemical Ocean Sections Study (GEOSECS) stations, and the observed delta13C values at each site differ substantially from regionally averaged GEOSECS delta13C profiles. We discuss the possible causes of these differences, including horizontal variability, near-bottom effects, and problems with the Pacific GEOSECS delta13C data. We also measured the isotopic composition (C and O) of core top C. wuellerstorfi from a depth transect of cores at each location. The delta18O data are used to verify that our samples are Holocene. Comparison of foraminiferal and bottom water delta13C values shows that this species faithfully records bottom water delta13C at both sites and demonstrates that there is no depth-related artifact in the dissolved inorganic carbon-C. wuellerstorfi delta13C relationship at these sites.
