Oceanography | Vol. 36, No. 2–3
In October 2023, we will celebrate the 50th anniversary of NOAA’s Pacific Marine Environmental
Laboratory (PMEL), a world leader in oceanographic research and the development of innovative
instrumentation and measurement strategies for monitoring and observing ocean conditions at global
scales. Through the collective efforts of PMEL and its national and international research partners, our
researchers have fundamentally advanced the scientific understanding of climate variability and change,
extreme and weather events, the effects of climate change on marine ecosystems, ocean carbon and
sulfur cycles, ocean acidification, Arctic oceanography, tsunamis, and ocean-seafloor interactive pro-
cesses. During this same period, PMEL scientists and technicians have been advancing the science and
technology innovation necessary to expand our observational capabilities in order to provide coverage
over large sections of the ocean. These advances have profoundly shaped our understanding of Earth
system processes and have led to improvements in environmental prediction, climate assessments, and
weather and climate services.
As one component of PMEL’s 50th anniversary celebration, the PMEL team has been working with the
Oceanography editor to develop a special issue of the journal focused on highlighting the laboratory’s sci-
entific work over the last five decades. This special issue is divided into themes that delineate how PMEL
research and observations have contributed to the advancement of NOAA’s mission to understand and
predict changes in climate, weather, and oceans and coasts, and to share that knowledge and informa-
tion broadly. The special issue is organized along six themes, each of which has one or two guest editors.
The theme editors extend their most sincere thanks and appreciation to the lead authors and
coauthors, scientists, and staff who carried out the research and provided the data that are described in
the articles presented in this special issue. We especially thank Sarah Battle and Sandra Bigley for their
exceptional help with the preparation of the figures and editing of the manuscripts. We are grateful to
David Detlor, John Thibodeau, and Avi Litwack at the NOAA Fisheries Office of Science and Technology
and graphic designer Sandra Graubard for their additional support. We also want to thank Ellen Kappel,
Vicky Cullen, and Johanna Adams of The Oceanography Society’s Oceanography staff for their incredible
editing work, layout designs, and artwork suggestions that improved the manuscripts.
As a final note, it has been a special honor for me to spend most of my career working with the many
outstanding and dedicated individuals who I have had the privilege to call my friends and colleagues at
PMEL over the last 50 years. I have been truly blessed to have the opportunity to work with folks who
fully believe in the NOAA concepts of science, service, and stewardship.
