RED TIDE...WHEN I FIRST HEARD THESE TWO WORDS, WHAT CAME INTO MY MIND WAS THAT THE OCEAN LITERALLY TURNS TO RED AND IT IS BECAUSE OF THE BLOOD OF THE DEAD MARINE ORGANISMS BECAUSE ISN'T IT, WHEN AN OCCURENCE OF RED TIDE IS REPORTED, WE ARE PROHIBITED TO EAT IT BECAUSE OF THE TOXINS THEY MIGHT CONTAIN, BUT THEN, I STILL DO NOT KNOW WHAT CAUSES THE DEATH OF THOSE ORGANISMS, IT IS STILL A BIG QUESTION MARK (?) TO ME. MY THOUGHT ABOUT THIS MATTER WAS STILL SHALLOW AND VERY LITERAL THEN NOT UNTIL I ENTERED SECOND YEAR AND STUDIED BIOLOGY. THIS TOPIC WAS DISCUSSED AND WAS ELABORATED THAT IS WHY I ALREADY HAD ENOUGH OF THE THOUGHT THAT RED TIDE IS CAUSED BY BLOOD.HONESTLY SPEAKING, MY MIND WAS ENLIGHTENED JUST NOW, WHEN I AM A SECOND YEAR STUDENT, (IMAGINE THAT, OF MY 13 YRS. OF EXISTENCE, I BELIEVED THAT BLOOD IS THE MAIN CAUSE OF THIS PHENOMENON!)AND WAS INTRODUCED TO ALGAES.WELL, ENOUGH NOW OF MY 'INNOCENT' ACT AND EXPERIENCE, LET US NOW GO ON WITH MY REAL TOPIC.RED TIDE, WHAT IS IT? WHAT CAUSES IT? DOES IT HAPPEN ONLY NATURALLY OR HUMAN ACTIVITIES ALSO CAUSES IT? THESE ARE THE QUESTIONS WE'LL BE TRYING TO ANSWER AS WE GO ON WITH THE KNOWLEDGE I'VE GAINED FROM MY BIOLOGY SUBJECT AND WITH THE IDEAS I HAVE RESEARCHED.
RED TIDE IS JUST A NAME COMMONLY USED TO NAME THE PHENOMENON KNOWN AS ALGAL BLOOM.THIS IS AN EVENT WHEREIN MARINE OR FRESH WATER ALGAE RAPIDLY 
ACCUMULATE IN THE WATER COLUMN OR BLOOM.THESE ALGAE, MORE SPECIFICALLY PHYTOPLANKTON RELEASES PIGMENT ( A CAROTENOID) INTO THE WATER WHICH CAUSES THE DISCOLOURATION OF THE WATER SURFACE AND THIS IS ALSO THE SOURCE OF THE TERM RED TIDE.AS THE STRUCTURE OF THE ALGAE BREAKS DOWN AND RELEASES THE PIGMENT, IT IS USUALLY RELEASED ON THE DEATH OF THE BLOOM.PHYTOPLANKTON, AS WE ALL KNOW ARE SINGLE-CELLED, MICROSCOPIC ,PLAN-LIKE ORGANISMS PROTISTS .

IT IS NOT YET CLEAR ON WHAT REALLY CAUSES RED TIDE. IT IS STILL QUESTIONABLE IF IT JUST OCCUR NATURALLY BECAUSE IN OTHER CASES, THEY APPEAR TO BE A RESULT OF HUMAN ACTIVITIES. THERE ARE REPORTS THAT IRON FERTILIZATION MAY CAUSE THIS PHENOMENON WHEREIN THE METHOD OF GEOENGINEERING IS USED BUT THEN AS WHAT IS BELIEVED NOW, RED TIDE IS PURELY A NATURAL PHENOMENON.WHEN TEMPERATURE, SALINITY, AND NUTRIENTS REACH A CERTAIN LEVEL, A MASSIVE INCREASE IN KARENIA brevis ALGAE OCCURS.NO ONE KNOWS THE EXACT COMBINATION OF THESE FACTORS THAT CAUSES RED TIDE, BUT SOME DO BELIEVE THAT HIGH TEMPERATURE COMBINED WITH A OF RAINFALL AND WIND ARE USUALLY THE ROOT OF RED TIDE. STILL, SCIENTISTS AROUND THE WORLD STUDIES RED TIDE AT PRESENT.WELL, I'M DONE WITH MY BLOG NOW, I HOPE YOU ENJOYED READING IT AND YOU WERE ABLE TO GET SOME KNOWLEDGE FROM IT. AND REMEMBER, IT IS NOT CAUSED BY BLOOD OF DEAD MARINE ANIMALS...OKAY?!?!...
