The
original information about the tsunami alert came from the US. Geological Survey
and was reported
by the BBC news on second April 2014. Waves of approximately six feet hit some areas
of Chile that resulted in power
cuts, fires, and landslides. The
crushing walls and heart attacks
were the cause
of the many deaths reported after the tsunami. Chile has a long history of being the
most seismically active countries in the world.
Tsunamis are known to have adverse effects to the coastlines of the oceanic basin. They
arise as a result of submarine earthquakes.
Tsunamis scrape the sea beds
sediments and invertebrates, damages the coral reefs, and also
the coastal vegetation. They also
affect the mud
flats and the underwater ecosystems. An oceanographer would have an interest in the tsunami by trying to understand its magnitude and the ocean's
depth at the point of occurrence. The scientist would also want to know
the effectiveness of the
monitoring systems for such events. The
information in the article impacts the
way we think
about the ocean or the earth-ocean interface by helping in understanding the importance of living away from the
ocean coasts. The nature of the
earth-ocean interfaces affects the
magnitude of the tsunamis.
As a scientist, the article
poses serious questions that can form the basis of research.
Among them is; why the region close to the
epicenter, was not affected
by the tsunami. The
expectation is that at the
epicenter, the magnitude of the tsunami would be high. But it was
not the case for the tsunami that occurred. A further research is needed regarding the
effectiveness of the monitoring systems
to avoid further casualties. A good hypothesis for
a thesis topic derived from the article
is that there is no adequate preparation for tsunamis to people living along the coast.
Subject: Chemical pollution
The information about chemical pollution on the ocean
was obtained from the National Oceanography Center, which is a report from the Natural Environment
Research Council. The article
proposes that the increased human
use of the open
ocean for transport,
mineral extraction, and disposal poses
a threat of chemical pollution to the deep
ocean and all the ecosystems. Chemical pollution affects the marine environment especially the organisms
living in both the shallow and the
deep sea parts. The chemical pollutants increase stress to the organisms and thereby affecting
their metabolic rates and growth rates. An oceanographer
would find the article of interest since chemical pollution to the marine environment is risky and hence
an action has to be taken. The vast ocean
cannot dilute all the chemical pollutants in the ocean water. A scientist would be interested in knowing the extent of pollution
over the ocean water by the chemical
pollutants as well as ways of
minimizing the pollution. The information in the article is very beneficial
since it gives a description of the common forms of chemical
pollution on the deep ocean and
the effects out of that. Therefore, it
acts as a wake-up call to the concerned agencies in handling the issue.
As a scientist, the article
poses a number of questions. First, it raises the
issue of who is responsible for safeguarding the levels of pollution. Another question is how best we
can deal with chemical pollution since it seems to increase at a high rate. I would propose further research
on the potential impacts of the chemicals
released in the oceans to the living
organisms. It is important to understand the effects as a major
step in handling the issue.
A good hypothesis for a thesis
topic in the area is that there is little involvement of the mandated agencies
in dealing with pollution and its effects on the ocean waters.
Subject: Overfishing
The
original information about
overfishing arose from the
marine scientists and was then reported
by the CNN news segment. The article
claims that human populations continue to increase whereas the other
organisms continue to diminish significantly. Among them are the
more than one million species
living in the oceans. Overfishing, climate change, and pollution
are the major threats to the marine
environments. Overfishing is the
main threat to them and it results
to vanishing of some species
in the underwater. To an oceanographer, the issue raises
concern with the methods used in fishing
and the legislation
that deals with overfishing. A
scientist would want to know the effects
of overfishing to the ocean environment and also
the effect of the increasing acidic carbon dioxide gas to the marine ecosystems. The information has an impact on the way we
think about the ocean since it offers
a warning on the oceans being at a catastrophic collapse due to overfishing and
under-protection.
As
a scientist, the questions to ask are;
1. What
are the effective ways of handling the
issue of overfishing since it
is under protected?
2. How
should the public be sensitized to the dangers of overfishing?
I would propose
to carry out research to find out the best
methods of fishing without causing damage to the coral reefs. Most
of the methods used are destructive to the marine life
and the marine ecosystems. A hypothesis for a thesis report
would be that; there lacks adequate and enforceable legislation that can help to handle overfishing.
Subject: Ocean floor
sediments
The
article was reported by the Scientific American
magazine on July 13, 2012. It
proposes that having an understanding of the past history
of the planet could help to prepare people
for a hot future.
The low oxygen levels in the ocean due to the
seafloor sediments explain of
the high temperatures
in future. The reduced oxygen levels threaten the marine life
and humans who
depend on the ocean for food. The
article would be of interest
to an oceanographer since it helps
to relate what happens in the ocean
and the outside
environment. It serves
as a basis for further research work on global
warming as a result of marine sediments.
A scientist would want to know the
chemical reactions involved in the reduction
of oxygen from the sedimentation process.
As a scientist, the question
that may arise is the
applicability of the past recorded data in dealing with the current challenges
of global warming. Might there be shifting trends that may affect the conclusions made
using the previous
data. Follow up research work is necessary to ascertain the possibility
of global warming due to the marine sedimentation. The hypothesis for
a thesis topic would be that; marine sedimentation leads to increased global warming.
