Seagrass meadows are important sinks of organic carbon (Corg), in particular the near-surface Corg pool (? 15 cm) compared to deeper sediments. Near-surface is highly susceptible disturbance and loss atmosphere, however, inadequate accounting for variability this limits their uptake into frameworks. We therefore investigated spatial seagrass biomass across different geomorphic (estuary, lagoona...

Barrows et al. (Reports, 5 October 2007, p. 86) presented cosmogenic exposure dates and data from an ocean sediment core that challenge evidence for glacier advance in New Zealand during the Younger Dryas event. We use modeling of geomorphic processes to argue that their cosmogenic exposure dates are inconclusive.

This paper provides a brief review of airborne light detection and ranging (LiDAR) data for characterizing linear and planar geomorphic markers in tectonic geomorphology, including traces of active faults and surface deformation caused by earthquakes. Challenges and opportunities of LiDAR for the study of tectonic geomorphology and coseismic deformation are also discussed.
