Many students from underrepresented groups lack adequate opportunities and mentorship as they head through the “pipeline” to graduate school. Despite the need for unique perspectives in collaborative scientific research, ethnic minority students continue to “leak” from the system. Here, I present some points for consideration for academic professionals (including educators, administrators, and program managers), based on the first-hand experiences of successful minority scientists.
Methane, Manganese, And Helium In Hydrothermal Plumes Following Volcanic Eruptions On The East Pacific Rise Near 9°500n, Brooke Love, Joseph A. (Joseph Anton) Resing, James P. Cowen, John E. Lupton, Daniel J. Fornari, Timothy M. (Timothy Mitchell) Shank, Dondra Biller

As part of a rapid response cruise in May 2006, we surveyed water column hydrothermal plumes and bottom conditions on the East Pacific Rise between 9°46.0'N and 9°57.6'N, where recent seafloor volcanic activity was suspected. Real-time measurements included temperature, light transmission, and salinity. Samples of the plume waters were analyzed for methane, manganese, helium concentrations, and the δ13C of methane. These data allow us to examine the effects of the 2005–2006 volcanic eruption(s) on plume chemistry. Methane and manganese are sensitive tracers of hydrothermal plumes, and both were present in high concentrations. Methane reached 347 nM in upper …

Direct estimation of aboveground biomass with spectral reflectance data has proven challenging for high biomass forests of the Pacific Northwestern United States. We present an alternative modeling strategy which uses Landsat’s spatial, spectral and temporal characteristics to predict live forest carbon through integration of stand age and site index maps and locally calibrated Chapman-Richards curves. Predictions from the curve-fit model were evaluated at the local and landscape scales using two periods of field inventory data. At the pixel-level, the curve-fit model had large positive bias statistics and at the landscape scale over-predicted study area carbon for both inventory periods. Despite …
