Bowie Seamount, situated off the west coast of Canada at 53° 18′ N, 135° 39′ W, is a long northeast-trending, volcanic mountain comprising a series of intersecting ridges. These ridges may have grown from extrusions along intersecting fractures in the oceanic crust. Two terraces form the flattened summit of the volcano at approximate depths of 80 and 235 m. These are thought to be remnants of platforms produced by combined shallow-water vulcanism and wave erosion during Pleistocene and Recent times when sea level was lower than it is today. The last episode of volcanic activity on the summit occurred after the formation of the upper terrace which is probably no more than 18 000 years old. Samples dredged from the upper half of the volcano include: pillow fragments, fragments of non-pillowed flows, pillow breccias, bombs, tuffs, ash, and unsorted tephra. The rocks are mainly alkali olivine basalts, accompanied by a few intermediate rocks which are believed to have been derived by differentiation of the basaltic magma.

Humping/hollowing and flipping are land development practices widely used on the West Coast to overcome waterlogging constraints to pasture production. However, there is very limited information about how the resulting "new" soils function and how their properties change over time following these extreme modifications. We hypothesised that soil quality will improve in response to organic matter inputs from plants and excreta, which will in turn increase nutrient availability. We tested this hypothesis by quantifying the soil organic matter and nutrient content of soils at different stages of development after modification. We observed improvements in soil quality with increasing time following soil modification under both land development practices. Total soil C and N values were very low following flipping, but over 8 years these values had increased nearly five-fold. Other indicators of organic matter quality such as hot water extractable C (HWC) and anaerobically mineralisable N (AMN) showed similar increases. With large capital applications of superphosphate fertiliser to flipped soils in the first year and regular applications of maintenance fertiliser, Olsen P levels also increased from values
