title: Regional Assessment of Soil Change in the Southwest Pacific

authors: Baldock, J.A.

abstract: The Southwest Pacific region includes the 22 island nations of the Pacific1, New Zealand and Australia (Figure 15.1). The landscapes of the region are very diverse ranging from a large continental land mass through to tens of thousands of small islands across the enormous expanse of the southwest Pacific Ocean. There are extensive ancient flat lands through to some of the youngest and most tectonically active landscapes on the planet. Temperature and rainfall ranges are large because of the breadth of latitudes and elevations. As a consequence, the soils of the region are also diverse. The strongly weathered soils in humid tropical areas and the vast expanses of old soils across the Australian continent are particularly susceptible to disturbance and this is where some of the more intractable problems of soil management occur today.

title: Modelling the effects of Po River discharge, internal nutrient cycling and hydrodynamics on biogeochemistry of the Northern Adriatic Sea

authors: Spillman, C.M.

subjects: ELCOM–CAEDYM

abstract: This study investigates the coupling of physical and biological processes in the Northern Adriatic Sea through use of a dynamic mass balance approach derived from an interdisciplinary model of hydrodynamics and water quality. Emphasis is placed on modelling the role of nutrient inputs from the Po River and the response of phytoplankton concentrations and distributions, and basin-wide nutrient fluxes. The effects of riverine inflows, seasonal stratification and meteorological forcing were assessed with a dynamically coupled 3D hydrodynamic (ELCOM) and ecological (CAEDYM) model after validation with in situ field and remote sensing data. Model simulation results and mass balance calculations indicate a close coupling of physical and biological processes over a range of space and time scales. Comparison of fluxes from advection and particulate organic matter sedimentation indicate that nutrient and phytoplankton levels of the Northern Adriatic Sea are sensitive to variations in riverine nutrient loadings. A net total phosphorus accumulation of 4.61 × 10 kg⁶ was determined for the basin in 2002, with different climate scenarios and riverine nutrient loadings resulting in varied system responses reflected in this net TP accumulation. Changes in net accumulation of nutrients are considerably lower than variations in nutrient loadings, which suggests that the Northern Adriatic has substantial buffering capacity.

title: Ranapia Mokena: son of Mokena Hou

authors: Hart, Philip

abstract: Little is known of the early life of Ranapia Mokena. He owned land close to Thames and acquired interests in other blocks, which provided him with some income, but he was never wealthy, as indicated by his being sued for a series of small debts. He invested in a small way in mining at both Thames and Te Aroha, and even worked in one claim. His life was most notable for being a deacon in the Church of England.
Ranapia was another example of a rangatira who supported the Crown, as was illustrated by his becoming a member of the Thames Native Rifle Volunteers. Childless, in his old age he brought up a niece’s daughter.
