Currently‚ our planet is going through a series of significant climate events that is potentially leaving an impact. Global warming has been at the center of creating destructive climate change. By increasing the amounts of greenhouse gases‚ humans are creating an environment with hotter temperatures‚ melting ice caps‚ and rising sea levels. To add on‚ scientists are now worried that humans are potentially destroying the oceans by creating an acidic environment in the water. The acidic environment

apart causing deep cracks in the floor of the ocean. Seawater seeps into these cracks and is heated by the molten rock below the Earth’s crust. As the water heats‚ chemical reaction begin to occur‚ and oxygen and minerals are removed from the water. As it goes deeper and gets hotter‚ certain metals and sulfur dissolve into it‚ and then the fluid begins to rise. It gushes back to the ocean floor‚ meeting with the near-freezing‚ oxygen-rick seawater‚ causing more chemical

with carbonate ions ( CO3-2) and Bicarbonate (HCO3) ions are formed. Thus ocean acidification decreases carbonate ions; This causes a problem for marine ecosystems‚ because carbonate ions are essential factor to marine life. The acidity of seawater is determined by the amount of hydrogen ions in solution ‚ which is then measured on the pH scale. The higher the concentration of hydrogen ions in a solution‚ the lower the pH of the solution. As stated in the previous paragraph‚ carbonic acid

Introduction to the ecological niche of the mud whelk‚ Cominella Glandiformis Mud whelks that are being investigated belong to the Gastropoda class and Buccinidae family. This means that they are similar to snails‚ having muscular foot and a spiraled shell. Cominella Glandiformis is most widely distributed among the many Cominella spp. found in New Zealand. They live exclusively on moderately sheltered beaches‚ principally on shores of mud. These mud whelks are ubiquitous on enclosed mudflats‚ creeping

CHAPTER 6 PRETREATMENT AND CLEANING Pretreatment and cleaning are two independent processes that could also be related to each other at the same time. Such methods are crucial for seawater reverse osmosis for what they bring from cost and residence time reductions to the increase in the production quality. 6.1. Pretreatment Various pretreatment methods are used and they include: biofilter‚ subsurface intake systems‚ conventional treatment‚ biological activated carbon‚ and chlorine injection.

a burning sensation tingling through me. Glancing up through the blue waves‚ I can make out the hot sun‚ its rays beating down onto the seawater. I feel strange and very hot‚ and I wonder what is in store for me next. Water around me also becomes warm and before I know it something very strange happens… I’m going up! Yes‚ up into the air and out of the seawater. Slowly‚ I’m traveling upwards‚ towards the vast‚ cloudy sky above me. I glance around‚ hoping to spot some other raindrops in a similar

be able to drink the water that we need. Desalination is a great way to provide more water for people. Taking salt out of seawater will provide for lots of people. In Carlsbad‚California they are building a desalination project. This will provide a natural water source for people to drink. When it is completed the huge plant will turn as many as 56 million gallons of seawater each day into drinking

Effects of salinity on the survival of the Daphnia Introduction The Daphniidae daphnia is a freshwater crustacean from the branchiopod class that is common to most ponds‚ lakes‚ pools‚ streams and springs around the world. The water flea‚ as it is sometimes referred to‚ is very small in size growing to a length of less than ¼ inch‚ it has a flat back‚ a rounded belly‚ black round eyes and a pair of antennae (Kindersley‚ 2006). The Daphnia have leaf-like appendages used in respiration‚ filter

from brackish water‚ through pure seawater (30 to 40 ppt)‚ to water concentrated by evaporation to over twice the salinity of ocean seawater (up to 90 ppt).[4][5] An increase in mangroves has been suggested for climate change mitigation.[6][7] The intertidal existence to which these trees are adapted represents the major limitation to the number of species able to thrive in their habitat. High tide brings in salt water‚ and when the tide recedes‚ solar evaporation of the seawater in the soil leads to further
