Continuous-Thrust Circular Orbit Phasing Optimization of Deep Space CubeSats

Applied Sciences
The recent technology advancements in miniaturizing the primary components of spacecraft allow the classic CubeSats to be considered as a valid option in the design of a deep space scientific mission, not just to support a main typical interplanetary ...

ISASO2: recent trends and regional patterns of ocean dissolved oxygen change [PDF]

Earth System Science Data
Recent estimates of the global inventory of dissolved oxygen (DO) have suggested a decrease of 2 % since the 1960s. However, due to the sparse historical oxygen data coverage, the DO inventory exhibits large regional uncertainties over the interannual ...

Reconstruction of the underwater sound speed field of mesoscale eddies in typical sea areas based on the physically-constrained deep learning model

Applied Ocean Research
As a widespread dynamical phenomenon in the world’s oceans, mesoscale eddies significantly alter the temperature and salinity of water masses, leading to differences in the sound speed profile (SSP) within the eddies compared to the surrounding seawater.

Subsurface biogeochemical response to Hurricane Idalia within a cyclonic eddy and river plume–stratified environment

Frontiers in Marine Science
Satellite observations can reveal chlorophyll blooms in the wake of hurricane disturbances but their subsurface biogeochemical anomalies remain poorly described due to limited in situ observations. Here, we quantify the biogeochemical response across the

Research on the Lossless Data Compression System of the Argo Buoy Based on BiLSTM-MHSA-MLP

Journal of Marine Science and Engineering
This study addresses the issues of the limited data storage capacity of Argo buoys and satellite communication charges on the basis of data volume by proposing a block lossless data compression method that combines bidirectional long short-term memory ...

Quantifying the Contribution of Ocean Advection and Surface Flux to the Upper‐Ocean Salinity Variability Resolved by Climate Model Simulations

Geophysical Research Letters
This study examines the impact of ocean advection and surface freshwater flux on the non‐seasonal, upper‐ocean salinity variability in two climate model simulations with eddy‐resolving and eddy‐parameterized ocean components (HR and LR, respectively). We

Annual Review of In Situ Observations of Tropical Cyclone–Ocean Interaction in the Western North Pacific during 2023

Remote Sensing
We present a review of in situ observations regarding the interactions between tropical cyclones and the ocean in the western North Pacific for the year 2023. A total of at least 13 tropical cyclones occurred during this period.

Evidence of Increased Deep Ocean Warming From a Sea Level Budget Approach

Earth's Future
Assessments of the global mean sea level (GMSL) budget over the satellite altimetry era (since the early 1990s) have concluded that the GMSL budget is closed within data uncertainties until 2016. However, studies have shown that since then, the sea level

Simulating Argo float trajectories and along-track physical and biogeochemical variability in the California Current System

Frontiers in Marine Science
Trajectories of >1,600 virtual Argo profiling floats and their sampled variability in key ocean physical and biogeochemical variables are simulated using a 0.125° global ocean physical-biogeochemical model (NOAA GFDL’s MOM6-SIS2-COBALTv2) and an ...

A neural network algorithm for quantifying seawater pH using Biogeochemical-Argo floats in the open Gulf of Mexico

Frontiers in Marine Science
Within the Gulf of Mexico (GOM), measurements of ocean pH are limited across space and time. This has hindered our ability to robustly monitor and study regional carbon dynamics, inclusive of ocean acidification, over this biogeochemically variable sea ...
