12. SIGNIFICANT RESEARCH ACCOMPLISHMENTS
a. RECENT ACCOMPLISHMENTS
“Global Warming”: One major issue facing climate science and society is how much humans
have influenced global and hemispheric temperature. In 1999 Mann and colleagues published a
northern hemispheric temperature record based mainly on tree-rings showing unprecedented
warming in the last 1000 years, known as the hockey stick curve. Enormous controversy and a
search for longer non-tree ring temperature curves ensued. We developed a new geochemical
temperature proxy method and applied it to construct a 2000-year long Chesapeake Bay
temperature curve published in 2003. Since its publication this curve has been integrated into
hemispheric compilations published in Science, Nature and the Intergovernmental Panel on
Climate Change (IPCC) 2007 report allowing a comprehensive analysis of 20th century warming.
Rapid Sea-Level Rise: Published papers in 2007 in EOS and GRL on rapid sea-level rise into
Chesapeake and Tampa Bays 7000 and 8200 years ago. The 8.2 ka sea-level rise was the largest
(6 to 12 m) and fastest (3 to 5 times the current rate) sea-level rise during the Holocene period, it
provide guidelines on modern and future rates of sea-level rise.
Arctic Climate History: I participated in the historic 2004 Integrated Ocean Drilling Program
(IODP) cruise to North Pole that recovered the entire Cenozoic climate record of the Arctic
Ocean for the first time. Four papers were published in Nature in 2006 as a result of initial
investigations and a special volume of Paleoceanography is due out February 2008 as are other
papers. Much media coverage accompanied this cruise (see IODP website). My role was
shipboard foraminiferal and ostracode biostratigraphy, core description, and post-cruise
paleoceanographic interpretation.
Atlantic Estuaries Project & Chesapeake Bay Ecosystem Project: Chesapeake Bay is the
largest, most productive US estuary. Estimated clean-up costs are tens of billions of dollars;
millions of dollars are devoted annually to its management and restoration through Chesapeake
Bay Program (CBP). Prior to 1996, USGS lacked an integrated science program to provide CBP
information. Our projects were part of USGS integrated science in CB resulting in many
management, scientific, media products listed below.
Deep-Ocean Temperature, Climate Change & Biodiversity. The impact of climate change on
deep-sea biota was virtually unknown until I initiated research to examine climate and deep-sea
biodiversity in 1996. Results including recent studies with post-doc Yasuhara have been
published in Science, Nature, Geology, Paleoceanography, Ecology Letters, Deep-Sea Research,
Ecology and the Feb 5th cover article in the Proceedings of the National Academy of Sciences.
Work was written up in NY Times and the subject of a BBC broadcast (1997) leading to invited
presentations at many international and national meetings. Our work has influenced a large
community applying the Mg/Ca method and altered long-held theories about the stability of deepsea ecosystems, fostering new research into temporal variability in biodiversity.
b. OTHER CAREER ACCOMPLISHMENTS
6
PRISM Paleoclimate Project
In the late 1980s, studies suggested that “global warming” was upon us and that the Earth
might experience unprecedented warmth over the 21st century due to the impact of anthropogenic
carbon emissions. Despite its importance, there was no quantitative large-scale (global or
Northern Hemispheric) study of a period of global warmth needed to provide a reliable scenario
for future climate. On November 17, 1987, I gave a seminar at USGS on Pliocene global warmth
and I recommended to Dick Poore that we produce a paleoclimate reconstruction on a geological
period of warmth exceeding the present patterned after CLIMAP’s global reconstruction of the
last ice age. The early-middle Pliocene was a time of high sea level (low ice volume) and
extreme warmth in high northern latitudes. PRISM began with funding from the USGS Global
Climate Program in 1988 with 3 projects; I ran the Ocean Margins Project and served on the
steering committee (with R. Thompson, H. Dowsett and R. Poore) until 1993.
I conducted fieldwork for PRISM in Japan (including a 6-month NSF-funded long term
visit to Shizuoka University in 1991), Costa Rica, Iceland, and sites in the US. I led international
(US USSR) field trips to Pliocene outcrops in the Atlantic Coastal Plain, participated in USUSSR cooperative research on Pliocene climate (1990 visit to Moscow), and helped advise on
field work by co-project members in Chile, New Zealand, Alaska, Bolivia, and elsewhere. I
coordinated efforts to understand North Pole Pliocene climate with colleagues in Iceland, Japan,
Denmark, England and Wales.
Thanks to USGS program coordinators and project members, PRISM was successful in
producing an integrated global reconstruction of ocean and terrestrial climate, sea level and ice
volume. With climate model collaborators we provided an improved understanding of the role of
the oceans and atmospheric carbon dioxide in global climate. I wrote many papers and co-edited
two volumes related to PRISM (Quaternary Science Reviews 1991, Palaeo-3 1994). H. Dowsett
has successfully kept PRISM going producing new reconstructions now used by several climate
modeling groups and PRISM serves as a unique empirical global warming data set for a
worldwide community.
Office of Scientific Technology and Policy (OSTP)
In 1996, I was asked by President Clinton’s Science Advisor Jack Gibbons to serve as an
agency representative to OSPT during the 9 months leading up to the now famous and
controversial Kyoto Climate Treaty. At the Kyoto meeting, Vice President Gore and US
negotiators signed the first treaty designed to have enforceable limits on carbon emissions in
more than 150 countries, though it was not ratified by Congress. While at the Environment
Division at OSTP I provided the scientific input to the administration on issues of climate change.
During my tenure, OSTP initiated regional climate assessments on the impacts of climate change.
Approximately 18 separate assessments were made throughout the US, forming the basis for the
national assessment. I contributed to OSTP’s report “Science and Technology: Shaping the
Twenty-first Century” (a report to congress), the US Global Change “Our Changing Planet”,
internal administration reports on the impact of future climate change, and OSTP presentations to
many government, NGO, and industry organizations. Much of the policies made by OSTP
during Clinton/Gore administration has been revisited in 2007 by the National Academy, the
IPCC, and the scientific community.
13. SCIENTIFIC LEADERSHIP
7
Project Chief, Chesapeake Bay Ecosystem. I initiated and implemented interdisciplinary research
in Chesapeake Bay demonstrating that the USGS can achieve integrated science research
conducted by all four divisions. Our success led to my involvement in numerous Bay
committees and workgroups and national syntheses of estuarine processes (see 12a) and
served as an example for new efforts in Tampa Bay and elsewhere. Results have led to
hypotheses about the causes and impacts of climate change in our own back yard, the
Mid-Atlantic region, and attributed anomalous climate variability since the 19th century
partly to human greenhouse gas emissions. Our research also helped managers set
dissolved oxygen limits for EPA and the states of Maryland and Virginia and guidelines
for sediment reduction targets.
Cruise Chief Scientist. I initiated and carried out long sediment coring in Chesapeake Bay as part
of the 1999 IMAGES cruise of the 330-foot French ship R/V Marion-Dufresne. IMAGES
is an international program devoted to understanding the role of the oceans in climate
change. The Chesapeake coring was part of a three-month long cruise around the North
Atlantic Ocean and was the first IMAGES work in a shallow estuary. To accomplish this,
I brought together 19 US shipboard participants and 4 US agencies (USGS, EPA,
Maryland Geological Survey, Naval Research Lab) to co-fund coring June 21-23, 1999.
A French-US reception was held on board in port in Norfolk, Va., hosted by the French
Polar Institute, attended by USGS director, the head of the French Polar Institute, and
program leaders from NSF and other organizations. Numerous papers have been
published. The cruise success led to additional IMAGES coring in Tampa Bay (2002)
and Chesapeake Bay (2003).
Advisory Committee Member (1997-present). The Mid-Atlantic Regional Climate Assessment
(MARA), now Consortium for Regional Assessment (CARA). I started as a steering
committee member to guide this assessment of climate impacts on forests, coasts, biota,
hydrology etc. I also coordinated stakeholder sessions and follow-up evaluation meetings
at Penn State in 2001. A report edited by A. Fisher et al. “Preparing for a Changing
Climate: Mid-Atlantic Overview”, was published in March 2000 under the auspices of the
US Global Change Research program. In 2003, as a steering committee member, I helped
CARA develop a decision-making system for climate assessment.
Project Member, Florida Salinity Project. I challenged the paradigm that early – mid 20th century
canal building in the Everglades caused salinity changes in parts of Florida Bay by
demonstrating that interannual and decadal changes in precipitation were related to largescale (i.e., El Niño-Southern Oscillation) climate patterns. We showed these processes
cause large-scale salinity and ecosystem changes, which had been attributed to human
activities. By providing a baseline of natural conditions, our results have played a role in
South Florida Water Management District, National Park Service and Army Corps of
Engineers efforts to re-engineer the Everglades to more natural conditions.
Project Chief. Deep Sea Circulation and Biodiversity.Project. I investigated this previously
unknown subject through detailed study of deep-sea temperature and biodiversity changes
in the Arctic and North Atlantic Oceans (see 12a).
8
PRISM Steering Committee and Project Chief. The initiative I provided and scientific
leadership during five years contributed to the efforts of many colleagues to make the
PRISM project the flagship of USGS Global Change research (see 12a).
MMS/VIMS/USGS Continental Shelf Sands. In collaboration with Virginia Inst. Marine Science,
with funding from MMS, we conducted environmental studies of the sandy habitats on the
continental shelf off Virginia Beach.

L20603, doi:10.1029/2007GL031318
Significance: Demonstrated rapid climatic and sea level change in eastern U.S. Eastern US
experienced decadal climate extremes in Chesapeake Bay temperatures and salinity, which
suggest natural and anthropogenic influence on regional climate. During the Medieval Warm
Period, the region was relatively warm, followed by major cold periods during the Little Ice Age.
Severe droughts alternated with extreme wet periods impacting Chesapeake Bay, its biota and
watershed. Climate oscillations can exceed anthropogenic influence related to land clearance.

H. Okahashi, B. K. Linsley. 2008. Abrupt climate change and collapse of deep-sea
ecosystems. Proceedings of the National Academy of Sciences 105 (5), 1556-1560
Significance: Challenged hypothesis from 1960s that deep-sea biodiversity was stable over long
periods of time and caused by stable bottom environments. Demonstrated that the number of
species living in the deep North Atlantic Ocean oscillated during 10 Milankovitch climatic cycles
in phase with global Pleistocene ice age cycles. Hypothesized that temperature, temperaturerelated factors and/or food resources were responsible for observed patterns; recently confirmed
with Yasuhara for abrupt climatically-induced catastrophic ecosystem change at centennial
timescales. This work influences international efforts to analyze the last great frontier in Earth’s
biotic systems, those in the deep-sea.

Late Pliocene and Quaternary bottom water temperature change in the deep North
Atlantic. Science v. 270, p. 1347-1351
Significance: Developed ostracode Mg/Ca paleothermometry method to reconstruct past
changes in deep-sea temperature and discovered large-scale variability during Pliocene and
Pleistocene. Prior work on oxygen isotopes in foraminifers could not separate the relative
contribution of temperature, ice volume, and biotic factors to 18O/16O ratios. Ostracode Mg/Ca
ratios are influenced by water temperature in which the shell is secreted and provide an
“instantaneous” measure of past aquatic temperatures. We provided evidence for deep-ocean
temperature changes associated with glacial deep-water cooling and Pliocene global warmth. The
Mg/Ca method has since become an essential tool in paleoceanography.
