Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Impact of twin typhoons on the upper ocean environment across the Northwest Pacific ocean

open access: yesTropical Cyclone Research and Review
Two typhoons, Saola and Damrey, moved across the Northwest Pacific Ocean (NPO) between July 27, 2012, and August 4, 2012. During this period, the oceanographic response was studied. The study examined variations in Sea Surface Temperature (SST) and Mix Layer Depth (MLD) in response to twin typhoons using satellite data from QuickSCAT wind, reanalysis ...

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Hydroelectric Dams and the Decline of Chinook Salmon in the Columbia River Basin

open access: yes
The decline of chinook salmon runs into the mouth of the Columbia River in recent decades is thought to be partly attributable to the construction of hydroelectric dams. The purpose of this article is to estimate the magnitude of losses in chinook salmon

Preliminary results of high-frequency autonomous profiler observations for typhoon-ocean interaction study

open access: yes, 2019
Observations to study the interactions between ocean upper layers and tropical cyclones are very difficult and shipboard measurements are even impossible due to the severe storms and the huge waves. The possible substitutes are unmannedautonomous surface
