Assimilation of middepth velocities from Argo floats in the western South China Sea
No full textPrevious studies are mainly limited to temperature and salinity (T/S) profiling data assimilation, while data assimilation based on Argo float trajectory information has received less research focus. In this study, a new method was proposed to assimilate Argo trajectory data: The middepth (indicates the parking depth of Argo floats in this study, ~1200 m) velocities are estimated from Argo trajectories and subsequently assimilated into the Regional Ocean Model System (ROMS) using four-dimensional variational data assimilation (4DVAR) method. This method can avoid a complicated float trajectory model in direct position assimilation. The 2-month assimilation experiments in South China Sea (SCS) showed that this proposed method can effectively assimilate Argo trajectory information into the model and improve middepth velocity field by adjusting the unbalanced component in the velocity increments. The assimilation of the Argo trajectory-derived middepth velocity with other observations (satellite observations and T/S profiling data) together yielded the best performance, and the velocity fields at the float parking depth are more consistent with the Argo float trajectories. In addition, this method will not decrease the assimilation performance of other observations [i.e., sea level anomaly (SLA), sea surface temperature (SST), and T/S profiles], which is indicative of compatibility with other observations in the 4DVAR assimilation system.Mathematical Physic
Action Argo: adapting the Argo network to collect actionable data and advance intensity forecasts of storms
No full textHurricane intensification forecasts are critical for coastal communities to make appropriate decisions regarding storm impacts. The upper-ocean structure along the storm path is currently a major source of uncertainty in model intensity forecasts. Improvement requires assimilation of in-situ ocean profile data on an increased spatial and temporal scale. Argo Network profiling floats can be set into or out of a high-frequency (2.5 days) Action Argo mission ahead of storm passage to make more profiles available to ocean models. In 2021, 42 Argo floats were set to Action Argo mode to test this concept. Here we assessed a subset of these floats that collected data in the Gulf of Mexico ahead of Hurricane Ida. We analyzed the National Oceanographic and Atmospheric Administration (NOAA) Real-Time Ocean Forecasting System (RTOFS) model data before and after float assimilation to determine the effect these floats had on the ocean model ahead of storm passage. We found that after float data were assimilated, RTOFS improved in forecasting skill for metrics such as Potential Energy Anomaly, Mixed Layer Depth, and depth of maximum salinity. Our results demonstrate the potential for Action Argo floats to improve ocean forecasts of upper ocean mixing ahead of storm passage.M.S.Includes bibliographical reference
Argo Parahyangan Train Service Quality Improvement
Full text linkArgo Parahyangan train passenger volume declined since the opening of Highway Cipularang. This is due to the emergence of competing business that is passenger transport transportation travel point to point as well as inter-city buses. Due to continued losses, PT Kereta Api Indonesia combines two previously with Bandung-Jakarta route the Argo Gede and Parahyangan. It is intended to further save on maintenance costs and increases revenue. However, passenger trains continued to decrease in volume as the growth of business travel point to point.To find out what the cause of the increase in passenger volume reduction, is necessary to find the root cause of the problem first. Needs to be analyzed from all sides as the analysis of the company's external and internal analysis of the company. External analysis conducted by analyzing Framework PESTEL and Porter's Five Forces. Internal analysis conducted by analyzing corporate strategy, business strategy, Segmenting Targeting Positioning (STP), and the marketing mix (7P) PT Kereta Api Indonesia.

The definitive version was published in Oceanography 30, no. 2 (2017): 18–28, doi:10.5670/oceanog.2017.213.The Argo Program has revolutionized large-scale physical oceanography through its contributions to basic research, national and international climate assessment, education, and ocean state estimation and forecasting. This article discusses the present status of Argo and enhancements that are underway. Extensions of the array into seasonally ice-covered regions and marginal seas as well as increased numbers of floats along the equator and around western boundary current extensions have been proposed. In addition, conventional Argo floats, with their 2,000 m sampling limit, currently observe only the upper half of the open ocean volume. Recent advances in profiling float technology and in the accuracy and stability of float-mounted conductivity-temperature-depth sensors make it practical to obtain measurements to 6,000 m. The Deep Argo array will help observe and constrain the global budgets of heat content, freshwater, and steric sea level, as well as the full-depth ocean circulation. Finally, another extension to the Argo Program is the addition of a diverse set of chemical sensors to profiling floats in order to build a Biogeochemical-Argo array to understand the carbon cycle, the biological pump, and ocean acidification.S.R.J. was

Argos' edible campus
No full textFood insecurity has been a growing problem on university campuses everywhere in the U.S. Food for a nutritional diet can be a lot harder to come by whether it be because of the cost or basic accessibility. When students at universities don't have reliable access to nutritional and affordable foods, this is called food insecurity. Specifically at UWF, 30% of students perceive themselves as food insecure and the University of West Florida has created some initiatives in order to address this issue. The Argo Pantry is a student-run food pantry that is used to promote food security through donations of canned and preserved goods. The Community Garden at UWF was created under similar pretenses using the integration of food-producing plants into the surrounding landscapes to improve access to food. The Argo Pantry and the community garden are programs already in place to assist students on the Volunteers at the community garden UWF campus but are not Harvesting lettuce yet at the production level needed to effectively combat the food insecurity problem without additional assistance. Argos' Edible Campus serves as this additional assistance. Edible landscapes create a destigmatized way to provide for students and the community in addition to increasing knowledge on food insecurity and how to confront this issue. Argos' Edible Campus was created to further spread the integration of edible UWF student picking out food from landscapes around campus the Argo Pantry so that it may eventually support food security on the university's campus
The Argo Program : observing the global ocean with profiling floats
No full textAuthor Posting. © Oceanography Society, 2009. This article is posted here by permission of Oceanography Society for personal use, not for redistribution. The definitive version was published in Oceanography 22 no. 2 (2009): 34-43.The Argo Program has created the first global array for observing the
subsurface ocean. Argo arose from a compelling scientific need for climate-relevant
ocean data; it was made possible by technology development and implemented
through international collaboration. The float program and its data management
system began with regional arrays in 1999, scaled up to global deployments by 2004,
and achieved its target of 3000 active instruments in 2007. US Argo, supported
by the National Oceanic and Atmospheric Administration and the Navy through
the National Oceanographic Partnership Program, provides half of the floats in
the international array, plus leadership in float technology, data management, data
quality control, international coordination, and outreach. All Argo data are freely
available without restriction, in real time and in research-quality forms. Uses of
Argo data range from oceanographic research, climate research, and education,
to operational applications in ocean data assimilation and seasonal-to-decadal
prediction. Argo’s value grows as its data accumulate and their applications are better
understood. Continuing advances in profiling float and sensor technologies open
many exciting possibilities for Argo’s future, including expanding sampling into
high latitudes and the deep ocean, improving near-surface sampling, and adding
biogeochemical parameters.The authors and their part of
