Summit, Greenland lock in zone methane and total air content data

Edward Brook
Total air content and methane concentration in the lock in zone of an ice core collected at Summit, Greenland. These data were collected to study the processes that trap air in polar firm. The lock in zone is the region where air transport stops and bubbles close off to trap air. The total air content and methane concentration in the closed porosity of ice samples were measured using a standard melt/refreeze method at Oregon State...

Greenland Summit 2013 Firn Air Results

Vasilii Petrenko, Jeffrey Severinghaus & Edward Brook
This data set contains measurements of 14C in CO2, CO and CH4 in firn air sampled at Greenland Summit. The main feature in the Δ14C of CO2 data is an increase with depth that reflects a smoothed atmospheric Δ14C of CO2 history. The highest Δ14C of CO2 value at 80.06 m sampling depth approximately coincides with the atmospheric 14C “bomb peak”, with signal smoothing from firn gas diffusion, as for other samples. The concentration of...

Biodiversity Point Contact Surveys

Rani Gaddam & Pete Raimondi
The Baseline surveys of rocky intertidal ecosystems (NC) project includes both Long-Term Monitoring and Biodiversity Surveys done in the North Coast of California. Long-Term Monitoring Surveys use fixed plots to document changes in percent cover, or abundance of targeted species or species assemblages. This fixed-plot approach allows the dynamics of rocky intertidal species to be monitored with reasonable sampling effort and provides sufficient statistical power to detect changes over space or time. Biodiversity Surveys provide...

Community Surveys: Swath Surveys

Jenn Caselle, Jeremy Claisse & Dan Pondella
Invertebrate and algae surveys are comprised of two components, sampled along the same transects: (1) uniform point contact (UPC) estimates of benthic cover and substrate characteristics and (2) swath transects to estimate the density of kelps and macroinvertebrates. This metadata record documents the swath surveys for the South Coast Baseline Program subtidal community surveys of of kelp and shallow reef ecosystems. Swath sampling consists of recording the number of selected invertebrate and algal species on...

Motile Invertebrate Size Counts

Jason Lopiccolo, Joe Tyburczy & Sean Craig
The North Coast region's rocky intertidal habitat is home to an exceptional diversity of algae and invertebrates. The main objective of this project is to produce a baseline characterization of this important ecosystem in the region and compare sites inside and outside of MPAs. Researchers will document abundance, and distribution of invertebrates and algae, and will describe the rocky habitat (e.g., rock type and surface roughness). In addition, this project will generate a fish biodiversity...
