Desert Dunes Transformed By Wind Regimes

Image 1. The image displays four different versions of wind currents transforming the desert dunes. The arrows on each example indicate the wind blowing direction to change the desert dunes. (Bass, 2022). 

This article provides information on the investigation of Desert Dunes and the impact of the wind regimes. The four major wind regimes are called Star, Barchan, Linear Self, and Transverse Crescentic. The most common wind regime is Barchan. The researchers gathered satellite images to gather data on the effects wind erosion has on the future of Earth. These wind regimes have a major impact on soil productivity and ecological richness (Bass, 2022). In addition, this is caused by climate change. The increase in temperature and lack of rain allows the sand to be easily maneuvered. The changing of the wind climate has produced overgrazing on the grasslands. Sand dunes provide great help to species that live near the coastal regions. The sand acts like a barrier to protect the communities from erosion that can lead to hazardous events, like flooding and storm damage. These events can lead to endangered species, habitats, and vegetation. Therefore, the more wind erosion there is, the more it impacts us all on Earth. Thus, reducing the movement and transformation of the sand dunes by attempting to control climate change can allow the sand dunes to do what it is intended to do; protect the coastal regions.

Coral Reef Service Providers

Image
By: Luis Castillo  Image 1: A diver using an XL Catlin Seaview SVII camera allowing a panoramic 360 ° frame, allowing self navigation for virtual divers  (XL Catlin Seaview Survey, 2015). Ecosystem servicing is an analytical field of environmental science that has come a long way for habitat conservation in efforts to counter the detrimental effects of the anthropogenic era. This research calls for a comprehensive approach encompassing coral reef sustainability, specifically -the reality that social and ecological systems are symbiotic and thus: should be met with an angle that asserts both dynamics for the future existence of coral reef ecosystems. Coral reefs and its service providers, or the ecological units that comprise these ecosystem services (Woodhead et al. 2018), are minimally understood -yet the benefits of these are known to be bountiful. Solar energy dissipation, ocean water nutrient eutrophication,  fishery services, coastal protection from extreme weather e...

High amounts of atmospheric mercury pollution from artisanal gold mining are captured by amazon forests

Image
 What I found interesting within this article would be the results from burning Hg-gold amalgams. It is unknown how Hg travels across regional landscapes. The mercury was being stored and deposition in a significantly affected area of artisanal gold mining in the Peruvian amazon. The gold mining received extreme high mercury inputs and have increased levels of total mercury and methylmercury in the air canopy vegetation and soils. They noticed a minimal difference between the sites and the low hg flux while the season changed. This difference was found to have come from a higher intensity within mining and dust generation which was found during the dry season. This increased deforestation and the volume of precipitation to be low while the dry season occurs. The Hg inputs that were found in the ASGM in the Peruvian Amazon are primarily deposited to the terrestrial ecosystem. The implications that the article states is that there is a large quantities of Hg that has been stored in t...

Relative Abundance of Floating Plastic Debris and Neuston in the Eastern North Pacific Ocean

Image
Even though there are increasing research based on ocean plastic pollution over the past decade, there seems to be little that we known about our current knowledge of how floating plastic debris is accumulating in subtropical oceanic gyres and how they may harm the surface associated pelagic community that is most known as neuston. By removing the floating plastic debris from the surface, we can minimize different effects of the pollution that can occur in a neuston. The results show that the dominant species of neuston such as pteropods, isopods, heteropods, and crabs show low atmospheric attributes which can be associated with the fitness benefit such as increased surface area. The research found strategies that can help remove the floating plastic from the ocean and reducing the negative effects of the neuston population.                                        ...
