Diazotrophic bacteria can reduce N2 into plant-available ammonium (NH4+), promoting plant growth and reducing nitrogen (N) fertilizer requirements. However, there are few systematic studies on the effects of diazotrophic biological fixation (BNF) contribution rate host N uptake metabolism. In this study, interactions Paenibacillus beijingensis BJ-18 with wheat, maize, cucumber were investigated when it was inoculated to these seedlings grown in both low high soils, un-inoculated plants as...
Tropical instability waves (TIWs), one of the most prominent mesoscale oceanic phenomena in tropical Pacific, play important roles climate and ecosystem. Due to limited observations difficulty estimating equatorial current velocity, long-term changes TIWs remain unknown. Rather than geostrophic equilibrium (Bonjean Lagerloef, 2002), TIW currents exhibit a momentum balance between inertial forces (local accelerations advections), Coriolis force pressure gradient force. Using shallow...
Near-inertial oscillations (NIOs) are widely observed dynamic motions in the global ocean, with a frequency related to earth’s rotation. Using particle trajectory model, we found combined influence of mesoscale eddies and NIOs could produce distinctive flower-like trajectories, which special case near-inertial trajectories were by surface drifters released within an anticyclone eddy South China Sea 2021. The energy budget indicates that wind geostrophic currents crucial generating...
The Great Whirl (GW), a prominent anticyclonic gyre in the northwest Indian Ocean, is crucial regional circulation and energy dynamics during summer monsoon. Using satellite observations high-resolution ocean simulations, this study examines mechanisms behind growth maintenance of Eddy Kinetic Energy (EKE) GW region. EKE peaks about 56 days after monsoon’s peak, delay caused by transfer processes. Southwest wind forcing monsoon initiates growth, with barotropic conversions from...
Most diazotrophs fix nitrogen only under nitrogen-limiting conditions, for example, in the presence of relatively low concentrations NH 4 + (0 to 2 mM). However, Paenibacillus sabinae T27 exhibits an unusual pattern regulation fixation, since although nitrogenase activities are high conditions 3 mM ) and repressed sufficiency (4 30 ), activity is reestablished when very levels (30 300 mM) present medium. To further understand this fixation regulation, we carried out transcriptome analyses P....
Abstract Mesoscale activities over the equatorial Pacific Ocean are dominated by Rossby and Yanai modes of tropical instability waves (TIWs). The TIW-induced surface velocity has not been accurately estimated in previous diagnostic models, especially for meridional component across equator. This study develops a model that retains acceleration terms to estimate TIW from satellite-observed sea height. Validated against moored observations, equator is first time, much improved existing...
Abstract Energetic mesoscale eddies (vortices) associated with tropical instability waves (TIWs) exist in the eastern equatorial Pacific Ocean between 0° and 8°N. This study examines seasonal variations eddy kinetic energy (EKE) of TIWs using situ satellite observations elucidates underlying dynamical mechanisms. The results reveal that cross-equatorial southerly winds are key to sustaining high-level EKE (up ~600 cm 2 s −2 ) from boreal summer winter 0°–6°N 155°–110°W. Because β effect...
Abstract In early August 2018, a record‐setting marine heatwave (MHW) occurred along the coast of Southern and Baja California. Water temperature at Scripps Pier rose to 26.4°C, highest in 102 years measurements. This paper investigates large‐scale ocean‐atmospheric conditions for this California MHW event. intense sustained event is result superposition “weather” timescale warming by coastal wind relaxation intraseasonal coastally trapped waves. For weather‐scale warming, climatological...
Abstract The summer intraseasonal oscillation (ISO) is characterized by a northward-moving rainband in the Indo–western Pacific warm pool region. physical origin of ISO not fully understood, as it masked strong interaction convection and circulation. This study examines to interannual variability during June–August over results show that tropical northwest anomalous anticyclone (NWP-AAC) fundamental mode on both time scales, destabilized monsoon mean state, specifically through barotropic...
Biological nitrogen fixation, a process unique to diazotrophic prokaryote, is catalyzed by the nitrogenase complex.

Of genes, 11 genes (nifB, nifH, nifD, nifK,...
Abstract Using an eastern tropical Pacific pacemaker experiment called the Ocean–Global Atmosphere (POGA) run, this study investigated internal variability in sea surface salinity (SSS) and its impacts on assessment of long-term trends. By constraining temperature with observations, POGA successfully simulated observed SSS. The trend SSS shows a general pattern salty regions becoming saltier (e.g., northern Atlantic) fresh fresher, which agrees previous studies. 1950–2012 is modulated by...
Abstract Subsurface eddies are a special type of oceanic eddy that display the maximum velocity in subsurface layer. Based on field observations, lens-shaped anticyclonic (SAE) was detected northern South China Sea (SCS) May 2021. The SAE located between 20 and 200 m, with shoaling seasonal thermocline deepening main thermocline. Satellite images showed exhibited positive sea level anomaly (SLA) negative surface temperature (SST) anomaly. Eddy track indicated this originated from Luzon...
Abstract Enhanced mesoscale eddy activities or tropical instability waves (TIWs) exist along the northern front of cold tongue in eastern equatorial Pacific Ocean.

The seasonal‐varying enhanced EKE signals are found to expand westward from 100°W...
