Summary: A remarkably consistent upwelling circulation driven by cross-shelf buoyancy gradients, rather than traditional wind forcing, is observed on the southern New England inner shelf. This circulation is strongest in summer and plays a crucial role in cooling the inner shelf and facilitating cross-shelf exchange.

Summary: The boundary current system in the Labrador Sea plays a crucial role in regulating convection in the interior basin. Research has revealed persistent mesoscale variability in the West Greenland boundary current and identified intensified cyclones as the downstream manifestation of Denmark Strait Overflow Water (DSOW). Quantifying these cyclones has shown that they transport dense water and increase the transport of DSOW in the West Greenland boundary current.

Summary: Multigrain/polydispersity has a significant impact on turbidity currents, but the understanding of fluid-particle interactions is still limited. In this study, a computational fluid dynamics-discrete element method model was used to investigate the dynamics of bidisperse lock-exchange turbidity currents. The results showed that bidisperse transport and fine component transport can be distinguished during the evolution of the bidisperse turbidity current. Bidisperse segregation alters the collision process between dispersed phases, and the transport of fine particles is inhibited by both the lift force and the contact force produced by collision.

Summary: This study highlights the importance of considering ocean circulation in quantifying upwelling and its variability and change. The roles of Ekman and geostrophic transports in coastal upwelling change under global warming are investigated, with findings showing that neglecting geostrophic currents can lead to substantial inaccuracies in projections of coastal upwelling change in the California Current System.

Summary: Using models, this study investigated the variations of the Western Maine Coastal Current (WMCC) and its connectivity with the Eastern Maine Coastal Current (EMCC). The results showed that the WMCC is influenced by the extension of the EMCC and runoff from two rivers. The study also identified the formation of a sea-level dome and the emergence of a counter-WMCC, which had impacts on the connectivity. Additionally, the connectivity varied from year to year.

Summary: Meson and anti-meson mixing processes provide important constraints on models that contribute to flavor violating neutral processes. In electroweak SU(3)L x U(1)N models, processes involving flavor changing neutral currents gain contributions from gauge and scalar fields. This study investigates the contributions of a neutral scalar that mimics the standard Higgs and neutral gauge bosons Z' and Z to meson mixing processes, and compares predictions with experiments. The results determine the quark mixing matrices and constrain the mixing angles.

Summary: The study focused on water-mass transformation and underlying processes in the Orkney Deep in the Southern Ocean, showing that vigorous turbulent mixing drives density space transport focusing and lightening/densification of layers within a deep western boundary current. Turbulence operates with high efficiency within the current, characterized by a dissipation ratio exceeding the common value, primarily driven by strong turbulence acting on a transition from weakly stratified bottom boundary layer to well-stratified off-boundary waters.

Summary: Melting of the inclined base of an ice shelf into the ocean induces stable stratification and a buoyancy-forced sheared flow. A numerical model was used to study the relationship between shear, stability, and mixing, revealing that the boundary current development goes through different phases, eventually generating a relatively well-mixed turbulent layer.

Summary: In this study, year-long measurements were conducted using an array of instruments in the southern part of Yermak Plateau, northwest of Svalbard. The study revealed the structure and seasonal changes of ocean currents, as well as the amount of water transported into the Arctic. This is the first study to collect year-round data on this oceanic region.

Summary: This study presents 1D parametrizations of wind-driven turbulent mixing in the ocean surface mixed layer and discusses the advantages and disadvantages of different vertical diffusion coefficients. The results show that these models can be applied to studying the behavior of buoyant particles in the ocean.

Summary: Constan-flux saline and turbidity current experiments were conducted to study the impact of bed roughness and permeability on current propagation and turbulence characteristics. The results showed that the bed roughness and permeability affect the current velocity and turbulence, and interbed pores influence vertical fluid exchange. Bed roughness and porosity are related to the distribution of turbulent kinetic energy.

Summary: Observations of ocean surface waves along the northern coast of Alaska show a strong correlation with seasonal sea ice patterns. The presence of landfast ice near the coast attenuates waves formed farther offshore, causing delays in wave onset near shore. Corrections to the ERA5 reanalysis product, particularly in relation to landfast ice, have significant effects on long-term trends in coastal wave exposure.

Summary: The coastal current in the Gulf of Maine has two cores, offshore and nearshore, peaking in summer and spring respectively, influenced by tidal mixing, surface thermal stratification, and wind. The cores merge south of Pleasant Bay and then split again east of Mount Desert Rock, with the nearshore branch flowing along the coast and the offshore branch turning southward. The momentum balance analysis shows that the coastal current is primarily driven by the pressure gradient force, with the barotropic PG dominant offshore and the baroclinic PG increasing with depth.

Summary: When a sediment laden river flows into a stratified water body, the water mass can intrude as an overflow, interflow or underflow, depending on the density contrast. Different modes of sediment driven convection occur in each case.

Summary: This study examines the electronic properties of methylammonium lead tribromide and methylammonium lead triiodide single crystals through experiments and simulations, revealing a high background carrier density and various factors influencing the free carrier concentration. Effective activation energies for conductivity are determined experimentally, and intrinsic parameters such as mobility and trap and ion density are extracted from drift-diffusion model fitting, providing insights into charge-carrier transport for device optimization in optoelectronic applications.

Summary: This study quantifies primary production rates in the southeastern Bering Sea from 2016 to 2019 and finds that the majority of gross primary production (GPP) and net community production occur during the spring phytoplankton bloom. After the bloom, the water column experiences low GPP and net biological carbon consumption. Phytoplankton growth rates are commonly suppressed in late summer due to nitrogen limitation. This research provides important insights into seasonal variations of biogeochemical cycles, phytoplankton community growth rates, and carbon availability in the southeastern Bering Sea using high-temporal-resolution measurements.

Summary: Time series data from a moored array of sensors are used to describe the long-term mean circulation and seasonal variations on the West Florida Continental Shelf. The observations reveal a coherent shelf-wide circulation pattern with alongshore and down-coast flow, and a coastal jet separating an upwelling region from a downwelling region influenced by the deeper ocean.
