O.S. Rixford Manufacturing Company corporate stock book, 1883-1898.

Around 1837, Luther Rixford founded a tool manufacturing business (originally known as the Luther Rixford Manufacturing Co.) in East Highgate, Vermont, that specialized in manufacturing scythes and other agricultural tools. A branch of this business was established in Upper Bedford, Quebec, around the late 1840's. Subsequent generations of the Rixford family took over the operations of both facilities, and in 1857 Oscar S. Rixford renamed the company the O.S. Rixford Manufacturing Co. The company was incorporated in 1883. Around 1920, the O.S. Rixford Manufacturing Company (of Canada) was acquired by Welland Vale Manufacturing, in St. Catharines, Ontario. The Rixford Company in Vermont continued operations until 1956, when decreasing demand for the tools they manufactured caused them to close their doors.

Ann Eliza Hepburne Rooth fonds, 1837-1897

Ann Eliza Hepburne was born in Chippawa, Ontario, in 1821, to William Hepburne and Susan Shannon. In 1842, she married William Anthony Rooth in St. James Cathedral in Toronto. They continued to live in different parts of the Niagara region, including Drummondville, Welland and Port Colborne. William was the editor and proprietor of the Drummondville Reporter, as well as an accountant and insurance agent, and later worked for the Customs Service in Port Colborne. He died in 1878, and Eliza in 1899. Both are buried in Drummond Hill Cemetery in Niagara Falls, Ontario.

Indenture between William Dickson [Jr.] and Robert M. Wilson, February 7, 1859.

William Dickson (1799-1877) was the son of the prominent Niagara businessman and politician William Dickson (1769-1846). William was educated in Edinburgh, Scotland, and settled in Galt, Ontario, upon his return to Canada. His father had business affairs in Dumfries and Galt, which he left in his sons charge when he retired to Niagara in 1837. William had an older brother, Robert, and younger brother, Walter, both of whom served in the Militia and became involved in politics.

(Table 1) Nutrient concentrations and carbon isotopes of sea ice segments and brine sampled during Nathaniel B. Palmer cruises NBP98-07 and NBP06-08, Ross Sea

We examined controls on the carbon isotopic composition of sea ice brines and organic matter during cruises to the Ross Sea, Antarctica in November/December 1998 and November/December 2006. Brine samples were analyzed for salinity, nutrients, total dissolved inorganic carbon (sum CO2), and the 13C/12C ratio of Sum CO2 (d13C(sum CO2)). Particulate organic matter from sea ice cores was analyzed for percent particulate organic carbon (POC), percent total particulate nitrogen (TPN), and stable carbon isotopic composition (d13C(POC)). Sum CO2 in sea ice brines ranged from 1368 to 7149 µmol/kg, equivalent to 1483 to 2519 µmol/kg when normalized to 34.5 psu salinity (s sum CO2), the average salinity of Ross Sea surface waters. Sea ice primary producers removed up to 34% of the available sum CO2, an amount much higher than the maximum removal observed in sea ice free water. Carbonate precipitation and CO2 degassing may reduce s sum CO2 by a similar amount (e.g., 30%) in the most hypersaline sea ice environments, although brine volumes are low in very cold ice that supports these brines. Brine d13C(sum CO2) ranged from -2.6 to +8.0 per mil while d13C(POC) ranged from -30.5 to -9.2 per mil. Isotopic enrichment of the sum CO2 pool via net community production accounts for some but not all carbon isotopic enrichment of sea ice POC. Comparisons of s sum CO2, d13C(sum CO2), and d13C(POC) within sea ice suggest that epsilon p (the net photosynthetic fractionation factor) for sea ice algae is ~8 per mil smaller than the epsilon p observed for phytoplankton in open water regions of the Ross Sea. These results have implications for modeling of carbon uptake and transformation in the ice-covered ocean and for reconstruction of past sea ice extent based on stable isotopic composition of organic matter in sediment cores.

(Table 1) Concentration of iron, DIP and silicic acid in water samples taken during Nathaniel B. Palmer cruises NBP06-01 and NBP06-08 (CORSACS I+II), Ross Sea

The Ross Sea polynya is among the most productive regions in the Southern Ocean and may constitute a significant oceanic CO2 sink. Based on results from several field studies, this region has been considered seasonally iron limited, whereby a "winter reserve" of dissolved iron (dFe) is progressively depleted during the growing season to low concentrations (~0.1 nM) that limit phytoplankton growth in the austral summer (December-February). Here we report new iron data for the Ross Sea polynya during austral summer 2005-2006 (27 December-22 January) and the following austral spring 2006 (16 November-3 December). The summer 2005-2006 data show generally low dFe concentrations in polynya surface waters (0.10 ± 0.05 nM in upper 40 m, n = 175), consistent with previous observations. Surprisingly, our spring 2006 data reveal similar low surface dFe concentrations in the polynya (0.06 ± 0.04 nM in upper 40 m, n = 69), in association with relatively high rates of primary production (~170-260 mmol C/m**2/d). These results indicate that the winter reserve dFe may be consumed relatively early in the growing season, such that polynya surface waters can become "iron limited" as early as November; i.e., the seasonal depletion of dFe is not necessarily gradual. Satellite observations reveal significant biomass accumulation in the polynya during summer 2006-2007, implying significant sources of "new" dFe to surface waters during this period. Possible sources of this new dFe include episodic vertical exchange, lateral advection, aerosol input, and reductive dissolution of particulate iron.
