A Deep Plankton Imager is deployed off the deck of the research vessel Sikuliaq in the Gulf of 蜜桃影像 earlier this year. The device images water for zooplankton, uses acoustics to look at fish communities, and measures temperature, salinity, light, oxygen, nitrate, phytoplankton biomass, and particle abundance several times per second.

University of 蜜桃影像 Fairbanks scientists played key roles in a recently released report about the effects of climate change at dozens of long-term research sites around the world. 

The report, , reviewed four decades of data collected through the National Science Foundation鈥檚 Long-Term Ecological Research program. The LTER program findings explore the effects of climate change in four types of environments: marine, dryland, coastal, and forest and freshwater.

蜜桃影像 contributors to the include Glenn Juday, professor emeritus of forest ecology; Roger Ruess, professor emeritus at 蜜桃影像鈥檚 Institute of Arctic Biology; and Jeremy B. Jones, a professor of biology at IAB. Russell Hopcroft, a professor of oceanography at 蜜桃影像鈥檚 College of Fisheries and Ocean Sciences, contributed to the of the report. The research vessel Sikuliaq, a National Science Foundation ship operated by 蜜桃影像, played a significant role in LTER work in the Gulf of 蜜桃影像. 

The overview included data collected from the Bonanza Creek LTER, a boreal forest research site that 蜜桃影像 has maintained since the 1980s. It experienced the greatest increase in average annual temperature from 1980 to 2019, 0.70 degrees Fahrenheit per decade, of nine forest LTER sites.

Bonanza Creek has also had a sustained period of relatively wet summers in recent years, although it鈥檚 unknown if that will represent a long-term trend.

鈥淪cenarios of possible future climates don鈥檛 agree on important aspects of the direction of climate change in 蜜桃影像,鈥 Juday said. 鈥淕iven the outsized magnitude of change experienced in the boreal world already, interest in monitoring and understanding effects on ecosystems is likely to remain high.鈥

Moisture variability and air temperature have increased since 1930 at all of the 28 LTER sites, which span from the Arctic to Antarctica. Ecosystem responses to climate change are just beginning to emerge, according to the study, making 鈥渓ong-term research crucial to understand, mitigate, and adapt鈥 those changes.
