	abstract = {We present geophysical and core evidence showing how subsidence caused by forearc shortening has accommodated Late Pleistocene and Holocene sediments supplied to the tectonically active Waipaoa shelf (NZ), limiting off-shelf export during the early sea level highstand. The last glacioeustatic fall and subsequent rise exposed and then flooded a shelf segmented into subbasins separated by zones of uplift, leaving key stratigraphic markers of shoreline regression and transgression that vary strongly in character across the shelf. Highstand sediment isopachs tied to piston cores dated using tephra correlation and a radiocarbon age model provide a sediment budget at similar to 2000yr intervals from the mid-Holocene (similar to 5500 cal.yr BP) to present. Sediment load estimates from our shelf budget are in agreement with published model estimates for suspended sediment discharge from the Waipaoa River for the past 3000yr but, importantly, do not show the 6-fold increase in the Waipaoa{\textquoteright}s sediment output that began with human settlement 700yr ago and accelerated with deforestation over the last century. Bypassing of Waipaoa sediment to the slope may therefore be a recent phenomenon caused by unnaturally high sediment loads, a conclusion supported by data reported elsewhere in this volume. Our study also reveals evidence for (1) a relatively thick mid-shelf transgressive section deposited during the last eustatic rise that may correlate to estuarine sequences reported from numerous sites on the modern coastline of the North Island, (2) a slight decrease in total basin filling rates during the highstand, and (3) variability in the partitioning of highstand sediments between individual subbasins that may reflect differing degrees of tectonic accommodation.

	abstract = {The Poverty margin was sampled in 2005 and 2006 as part of an international initiative to examine the terrestrial and marine sedimentary response to natural and human impacts on dispersal systems at mud-dominated coasts: the NSF MARGINS Source-to-Sink Initiative. Pb-210 accumulation rates generally decrease from similar to 1 g/cm(2) y in the mid-shelf depocenter on the outer shelf to similar to 0.1 g/cm2 y on the mid-slope plateau (range 0.04-2.53 g/cm(2) y). Higher accumulation rates are observed all along the outer Poverty shelf, extending over the shelf break onto the upper Poverty slope in canyons and gullies. Rates are fast in gullies that incise into the shelf edge (0.75-1 g/cm(2) y), particularly in the area between Waipaoa Canyon and Poverty Canyon, and in the axis of Poverty Canyon (1.29-1.89 g/cm(2) y). Below similar to 1200 m water depth, rates in the axis of Poverty Canyon are no more rapid than those found at open slope cores in similar water depths (0.12-0.15 g/cm(2) y). Excess Pb-210 profiles generally exhibit steady state characteristics, except in the axis of Poverty Canyon, where non-steady-state Pb-210 profiles are observed. Cs-137 was not found above minimum detection limits or above statistical background levels in any cores from the Poverty margin. Be-7 was found distributed widely along and across the margin during both summer and winter periods, observed to depths of up to 4cm. Widespread presence of Be-7 on the margin in both winter and summer suggests that terrestrially derived sediment is reaching the outer shelf and upper slope throughout the year. A sediment budget based on Pb-210 accumulation rate data shows that approximately 13-18\% of the Waipaoa annual discharge is accumulating on the outer Poverty margin as a whole, and approximately 11-15\% of the annual discharge is accumulating on the continental slope alone. Notably, approximately 28\% of the sediment annually accumulating in the outer margin is being sequestered in slope gullies and canyons, although they represent only 6\% of the area of the outer margin.

	abstract = {Submarine canyons are major geomorphologic features on the Earth{\textquoteright}s surface. Their formation has received considerable debate, but their demise has received less attention. Research of modern canyons with cores and moorings has documented active sediment transport and deposition, but extrapolation of these local observations over larger areas is precluded by complex canyon geomorphology. High-resolution multibeam and chirp data presented here provide convincing evidence of an infilling canyon head on the Waipaoa River margin of New Zealand. Tens of meters of Holocene sediment have accumulated on the outer shelf and in Lachlan canyon as a result of off-shelf sediment transport. Regardless of the ultimate fate of this system over geological time scales, this research demonstrates highstand sedimentation as a possible mechanism for canyon burial and cause of canyon demise, which has important implications for the evolution of canyons globally.},
