Nature and origin of variations in late-glacial and Holocene atmospheric 14C as revealed by global carbon cycle modeling
(1990)Simulations with a global box-diffusion $\sp$C model indicate that the millennium- and century-scale atmospheric $\Delta\sp$C variations during the Holocene are more likely explained by fluctuations in $\sp$C production ... -
Petrology and structure of the pre-Tertiary rocks of Lummi and Eliza Islands, Washington
(1980)Exposed on Lummi Island are two groups of pre-Tertiary rocks everywhere in fault contact with each other: a 1300 meter thick section of turbidite sandstone and mudstone, and rocks largely of igneous affinity. The latter ... -
The role of oceanic lithosphere in inter- and intra-volcano geochemical heterogeneity at Maui Nui, Hawaii
(2004)The volcanoes of Maui Nui (West Molokai, East Molokai, Lanai, West Maui, Haleakala and Kahoolawe) record Hawaiian magmatism at ∼1--2 Ma. These volcanoes nearly span the compositional range erupted from all the Hawaiian ... -
The use of streambed texture to interpret physical and biological conditions at watershed, reach, and subreach scales
(1998)Physical controls on bed-surface grain size and consequent implications for aquatic habitat are examined at a variety of spatial scales. Data compiled from laboratory studies show that reach-average median surface grain ...
