Summary: This study conducted a closed-system batch reaction experiment to evaluate the effects of interaction between Gulf of Mexico seawater and Mississippi River sediments on dissolved rare earth elements (REE) concentrations and neodymium isotopic compositions (eNd). The results showed that the dissolution of labile phases of the river sediments significantly increased the dissolved REE concentrations in seawater, while secondary mineral precipitation lowered the concentrations. The study also highlighted the importance of river sediments in influencing REEs and eNd in seawater along continental margins.

Summary: Transport processes are important factors that modulate the estuarine and coastal geomorphology, biogeochemistry, water quality, and coastal food webs in river-dominated shelves of the Gulf of Mexico. These processes control the fate of river-borne sediments, nutrients, and carbon, influencing issues such as land loss, eutrophication, hypoxia, harmful algal blooms, and coastal acidification. Furthermore, transport of pollutants such as pesticides, herbicides, heavy metals, and oil into estuaries and coastal systems is also influenced by these processes. The Gulf of Mexico Research Initiative (GoMRI) has provided significant opportunities to study transport processes in the region and improve understanding for more accurate forecasting and response strategies in the event of environmental disasters such as oil spills.

Summary: A large dataset of historical surface drifter data from the Gulf of Mexico was collected, processed, and assimilated into a dataset called GulfFlow for studying circulation and variability in the region. The high-resolution mean surface current map obtained from GulfFlow provides a valuable resource, while direct bin-averaging of hourly drifter data was found to lead to severe artifacts due to the inhomogeneous temporal distribution of the drifters.

Summary: This article examines the impact of the Gulf Stream on the exchange of waters between the open ocean and the shelf, based on observations from instruments deployed in the South Atlantic Bight. The study finds that the position and transport of the Gulf Stream control the along-slope flow along the continental slope, and there is a wave-like meander influence on the shelf-edge currents in a specific frequency band.

Summary: This study uses 3-D, depth-migrated seismic data to analyze the structural architecture and evolution of eastern Mississippi Canyon in the northeastern Gulf of Mexico. The study finds that the movement of salt in this area was driven by a combination of gravity and differential loading forces, which varied in importance and direction over time. These findings are significant for understanding the more complex structures and evolution of the northern Gulf of Mexico.

Summary: The 2010 Macondo platform accident by BP resulted in one of the largest oil spills in history, lasting over three months and releasing nearly 500 million liters of oil. This accident exposed technological deficiencies in controlling spills in deep waters. To address the need for understanding and predicting large oil spills in the southern Gulf of Mexico, a consortium of researchers from Mexico and abroad launched an ocean observation project (2015-22) to establish an environmental baseline, enhance monitoring and computational modeling capabilities, and promote scientific understanding of the marine environment.

Summary: Global commercial catches of squid have increased greatly in recent years, but a significant portion of the catches remain unidentified. In the southeastern Gulf of Mexico, the squid catches are often not recorded and their species composition is unknown. This lack of knowledge hinders population evaluation and conservation strategies. This study used morphological and molecular identification tools to analyze the species composition, abundance distribution, and genetic structure of squid in the Yucatan Shelf. The results revealed a dominant species, identified as Doryteuthis pleii, and a continuous gene flow within the population.

Summary: Phosphorus control is crucial in mitigating eutrophication in aquatic ecosystems. However, our understanding of phosphorus dynamics along the land-ocean aquatic continuum and the lack of well-developed process models hinder effective control of phosphorus export from soils. This study coupled riverine phosphorus biogeochemical processes and water transport with terrestrial processes to assess the impact of environmental changes on phosphorus loading and export in the Mississippi River Basin. The findings emphasize the importance of adopting effective phosphorus management strategies to reduce soil erosion and improve phosphorus use efficiency in crop production.

Summary: Research indicates a northward shift of the Gulf Stream towards the Tail of the Grand Banks on the Northwest Atlantic Shelf in 2008, disrupting the connectivity of the Labrador Current and potentially contributing to abrupt warming and an ecosystem shift a year later. Historical observations suggest similar events may have occurred in the 1970s.

Summary: In this study, an unmanned aerial vehicle (UAV) was used to detect and map surface discontinuities with displacements of a few centimeters, indicating the presence of initial geological deformations. The study found that sediments of alluvial fans are susceptible to various tectonic and exogenous deformational processes, and the interpretation of ultra-high resolution UAV images can help recognize low-amplitude brittle deformations at an early stage. UAV surveys are critical for discerning neotectonic activity and its related hazards over short observation periods.

Summary: This article investigates optimal sample allocation in stratified random sampling for estimation of accuracy and proportion of area in applications where the target class is rare. The study finds that precision of estimated accuracy has a stronger impact on sample allocation than estimation of proportion of area, and the trade-offs among these estimates become more pronounced as the target class becomes rarer. The results provide quantitative evidence to guide sample allocation decisions in specific applications.
