“…The Stream Metabolism Program imports in situ DO, water temperature, and PAR time series data and adjusts the readings such that time intervals are consistent. Temperature and DO readings are corrected for instrument fouling and drift based on pre-and postdeployment instrument calibrations (Wagner et al 2006). DO saturation concentration is calculated at each time interval from DO concentration, water temperature, and barometric pressure data.…”

Stream metabolism was measured in 33 streams across a gradient of nutrient concentrations in four agricultural areas of the USA to determine the relative influence of nutrient concentrations and habitat on primary production (GPP) and respiration reach. When data for all study areas were combined, there were no statistically significant relations between gross primary production or community respiration and any of the independent variables. However, significant regression models were developed for three study areas for GPP (r 2 = 0.79-0.91) and CR-24 (r 2 = 0.76-0.77). Various forms of nutrients (total phosphorus and area-weighted total nitrogen loading) were significant for predicting GPP in two study areas, with habitat variables important in seven significant models. Important physical variables included light availability, precipitation, basin area, and in-stream habitat cover. Both benthic and seston chlorophyll were not found to be important explanatory variables in any of the models; however, benthic ash-free dry weight was important in two models for GPP.

“…With guidance from USGS personnel, USFWS personnel operated the monitors on site and serviced the monitors off site (RLWD Laboratory, Thief River Falls, Minn.). Accuracy ratings for water-quality records are presented in table 18 of Wagner (2006) and are based on combined sensor fouling and calibration drift corrections applied to the record. Accuracy ratings for this study were downgraded because of protocol issues beyond the control of USGS.…”

“…Four islands were selected for soil sampling based on disturbance history and accessibility: one in the Twin Cays range (East Island) and three in the Pelican Cays range (Manatee, Fisherman's, and Ridge Cays). Extent of natural and disturbed areas at each study location was estimated from satellite imagery (Landsat 7, May 2008; http://landsat.usgs.gov) and aerial photographs (April 2006(April , 2007 I. C. Feller, unpublished) and confi rmed by ground-truthing (May 2008).…”

“…Data are subjected to a quality assurance/quality control (QA/QC) process to remove outliers and invalid and suspect data before they are included in the historical archives. The QA/QC process also incorporates established criteria and procedures to correct for sensor and fouling drift (Wagner et al, 2006).The data have contributed to new and existing research studies, publications, and management programs for both Smithsonian researchers and an increasing number of organizations from the region (e.g., Renken and Mumby, 2009). …”

In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions in History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to ZoologyIn these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affi liation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes. For detailed submissions requirements and to review the "Manuscript Preparation and Style Guide for Authors," visit the Submissions page at www.scholarlypress.si.edu. The paper used in this publication meets the minimum requirements of the American National Standard for Permanence of Paper for Printed Library Materials Z39. Foreword N early two-thirds of Earth's surface is covered by the ocean, a global system essential to all life. Impacts on one part of the ocean can have worldwide effects. The ocean moderates our climate, provides valuable resources, and produces at least half the oxygen we breathe: it makes our planet livable. We know little, however, about the physical, chemical, geological, and biological aspects of this crucial life support system. s m i t h s o n i a n c o n t r i b u t i o n s t o t h e m a r i n S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E S MARINE BIODIVERSITY, EVOLUTION, AND SPECIATION S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E S i i i • S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E SThe Smithsonian Institution, in efforts to increase knowledge about the ocean, has established a ...
