Integrating stations from the North America Gravity Database into a local GPS-based land gravity survey
Thomas G. Shoberg, Paul R. Stoddard
2013, Journal of Applied Geophysics (89) 76-83
The ability to augment local gravity surveys with additional gravity stations from easily accessible national databases can greatly increase the areal coverage and spatial resolution of a survey. It is, however, necessary to integrate such data seamlessly with the local survey. One challenge to overcome in integrating data from national...
Effect of heterogeneous atmospheric CO2 on simulated global carbon budget
Zhen Zhang, Hong Jiang, Jinxun Liu, Weimin Ju, Xiuying Zhang
2013, Global and Planetary Change (101) 33-51
The effects of rising atmospheric carbon dioxide (CO2) on terrestrial carbon (C) sequestration have been a key focus in global change studies. As anthropological CO2 emissions substantially increase, the spatial variability of atmospheric CO2 should be considered to reduce the potential bias on C source and sink estimations. In this...

2013, Transactions of the American Fisheries Society (142) 362-372
Since Pacific salmon stocking began in Lake Michigan, managers have attempted to maintain salmon abundance at high levels within what can be sustained by available prey fishes, primarily Alewife Alosa pseudoharengus. Chinook Salmon Oncorhynchus tshawytscha are the primary apex predators in pelagic Lake Michigan and patterns in their prey selection...
On the halophytic nature of mangroves
Ken W. Krauss, Marilyn C. Ball
2013, Trees: Structure and Function (27) 7-11
Scientists have discussed the halophytic nature of intertidal plants for decades, and have generally suggested that inherent differentiation of an obligate halophyte from a facultative halophyte relates strongly to whether the plant can survive in fresh water, and not much else. In this mini-review, we provide additional insight to support...
Hydrography change detection: the usefulness of surface channels derived From LiDAR DEMs for updating mapped hydrography
Sandra K. Poppenga, Dean B. Gesch, Bruce B. Worstell
2013, Journal of the American Water Resources Association (49) 371-389
The 1:24,000-scale high-resolution National Hydrography Dataset (NHD) mapped hydrography flow lines require regular updating because land surface conditions that affect surface channel drainage change over time. Historically, NHD flow lines were created by digitizing surface water information from aerial photography and paper maps. Using these same methods to update nationwide...
