This study is the first detailed investigation of microplastics (MPs) ranging from 20 µm to 5 mm in surface waters coral reef ecosystems coast Cuba. A total 72 samples were collected 22 stations during scientific cruise "BOJEO CUBA 2024". The post-sampling treatment was based on enzymatic digestion organic matter and subsequent analysis MPs using laser direct infrared (LDIR) Chemical Imaging Spectroscopy. 2,616 11 types polymers have been identified, with a significant composition...
Abstract. Atmospheric water vapour has been acknowledged as an essential climate variable. Weather prediction and hazard assessment systems benefit from real-time observations, whereas long-term records contribute to studies. Nowadays, ground-based global navigation satellite system (GNSS) products have become widely employed, complementing observations over the oceans. Although past decade seen a significant development of GNSS infrastructure in Central South America, its potential for...
The present-day deformation of the earth crust in Argentine part Tierra del Fuego main island (southernmost South America) is here investigated based on repeated geodetic GPS observations. traversed by active transform boundary between American and Scotia tectonic plates, represented Magallanes-Fagnano fault system. Since 1993 a regional network comprising to date 29 sites has been observed almost every year. complete set accumulated observations was processed using Bernese software...
Abstract Taking advantage of the public Global Navigational Satellite Systems (GNSS) infrastructure in South America, an operational monitoring system for total electron content (TEC) ionosphere has been developed. It incorporates data near real time, from more than 90 GNSS satellites tracked by 200 ground stations. In turn, produces every 15 min a snapshot, that is map, current state regional ionosphere, which immediately available online. These maps could be employed, example, to augment...
Abstract Cyclone Xaver pounded the North Sea on 5–6 December 2013 and reached its maximum in German Bight second day. Combined geodetic measurements from SARAL/AltiKa satellite a local network detect cross‐shelf alongshore variations loading vertical deformation. The root‐mean‐square differences between observations predictions are 30 cm for surge height, 2 m significant wave 4 m/s wind speed, with biases. different forcing mainly causes predicted height differences. smallest standard...
Based on precise pressure tide gauge observations lake-level records are derived for two sites in Lago Argentino, southern Patagonia, of 2.5 and 1 years duration. Applying the tools time series analysis, principal processes affecting lake level identified quantified. Lake-level changes reflecting variations volume dominated by a seasonal cycle 1.2 m amplitude. Lake-volume occur addition with daily period response to melt water influx from surrounding glaciers. Sporadic lake-volume jumps...
We demonstrate the application of a 100 km long lake as sensor for studying tidal effects on Tierra del Fuego main island. The lake‐level variations observed in Lago Fagnano reflect both direct response to potential and indirect effect ocean loading. Modeling contributions explains signal about 70%. Underestimated model load tide amplitudes are found be probably responsible remaining difference. interpret this discrepancy hint regional elastic lithosphere properties differing substantially...
Annual and seasonal diurnal precipitable water vapor (PWV) variations over Central South America are analyzed for the period 2007–2013. PWV values were obtained from Global Navigation Satellite Systems (GNSS) observations of sixty-nine GNSS tracking stations. Histograms by climate categories show that temperate, polar cold dry have a positive skewed distribution tropical climates (except monsoon subtype) negative distribution. The surface temperatures (T) anomaly datasets using principal...
The lake-level variations of Lago Fagnano, the largest lake in Tierra del Fuego, southernmost South America, on time scales from a few minutes to three years are investigated using geodetic approach and applying tools series analysis. Based pressure tide gauge records at locations precise derived. analysis observed space, frequency domain leads separation principal force-response mechanisms. We show that Fagnano can be described essentially as combination shift tilt surface seiches....
Development of regional services able to provide ionospheric total electron content (TEC) maps with a high spatial resolution, and in near real-time, are importance for applications the research community. We here methodologies, preliminary assessment, such system. The system relies on public Global Navigational Satellite Systems (GNSS) infrastructure South America, it incorporates data from multiple constellations (currently GPS, GLONASS, Galileo BeiDou), employs frequencies, produces...
Abstract We integrate geodetic, geological and seismological observations in Tierra del Fuego, into a consistent quantitative analysis, to better understand the current crustal deformation associated Magallanes‐Fagnano Fault, that is, transform boundary between South American Scotia plates at southern tip of Patagonia. To obtain reliable geodetic estimates thickness seismogenic layer, we model seismic cycle from great 1949 M w ≃ 7.7 earthquake present, including lasting effects postseismic...

In this study, we present the results of an analysis morphological features Equatorial Plasma Bubbles (EPBs) over South America. context, analyzed data from Disturbance Ionosphere indeX (DIX) maps calculated using around 450 Global Navigation Satellite System (GNSS) stations. To mitigate influence magnetic disturbances on bubble development, only geomagnetically quiet days were utilized.

[1] The comments of Bos [2010] are valuable and certainly contribute to an improved understanding the tidal interactions in Tierra del Fuego. They based on a thorough examination subject emphasize scientific relevance this investigation. [2] [2010, Figure 2] presents modelled lake-tide predictions that differ from those given our article. reason for difference consists essentially incorrect phase lags direct effect as by Richter et al. [2009, 2a]. Due inconsistencies between used ETERNA...
Abstract. Vertical site velocities determined by geodetic GPS observations in the Lago Fagnano area, Tierra del Fuego main island, are interpreted with respect to their potential relation glacial-isostatic crustal response ice mass changes. The spatial pattern of uplift rates, combination horizontal deformation pattern, point towards a fault-tectonic rather than origin vertical deformations. This implies small GIA effects pointing relatively Holocene ice-mass changes Fuego. However, these...
