1. Waves transfer energy through water in the ocean. Individual water particles move in circles as a wave passes by rather than moving forward with the wave.
2. Key characteristics of waves include the crest (highest point), trough (lowest point), wavelength (distance between crests), and wave height (distance between crest and trough). Wavelength determines wave speed and how deep the wave disturbs the water.
3. As waves approach shore they slow down and steepen, eventually collapsing in breakers where the crest curls over. Tides are caused by gravitational attraction of the Earth, Moon, and Sun, and vary in daily and monthly cycles.
Erosion is when wind, water, and ice take sediments away.
Erosion on coasts by wind and water.
Water is major agent of erosion.
About 21% of all erosion in done by coastal erosion.

Waves are never ending dynamic surfaces created by the action of wind on ocean surfaces. Waves are undulations of the surface layers of bodies of sea waters. Large bodies of water are almost constantly in motion. Ocean surface are never calm and smooth.They are uneven, irregular, rough and restless. Sea waves are defined as undulations of seawater characterized by unique features. Waves are moving energy patterns. They travel along the interface between ocean and the atmosphere.
A PowerPoint about storm surges and how it affects the weather. A brief case study about storm surges in the North Sea and Bangladesh are also included.

Oceans are a vast body of salt water that covers almost three to fourths of the earth's surface.
Seas are smaller, found on the margins of the ocean and are partially enclosed by land.
Seawater:
High density, high heat capacity, colder, salty and slightly compressible (its volume decreases under pressure), thus its density increases with pressure.
Why is Ocean Circulation Important?
•Similar to winds in the atmosphere, they transfer significant amounts of heat from equatorial areas to the poles and thus play important roles in determining the climates of coastal regions.
•The ocean circulation pattern exchanges water of varying characteristics, such as temperature and salinity
•ocean currents and atmospheric circulation influence one another.
•in addition, they transport nutrients and organisms

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2. Waves
A wave is a rhythmic movement that
carries energy through space or
matter, such as ocean water.
2
3. Waves
In deep water, a wave is a forward
motion of energy, not water. In fact,
the water does not move forward with
a wave. If we followed a single drop
of water during a passing wave, we
would see it move in a circular pattern
returning to a point near its original
position at the wave’s end.
3
4. Wave Characteristics
• A crest is the highest point of a
wave.
• A trough is the lowest point of a
wave.
4
5. •The vertical distance between crest
& trough is the wave height.
•The horizontal crest-to-crest
distance is the wavelength.
5
Wave Characteristics
6. Wave Characteristics
• The wavelength determines the
wave base, which is the depth to
which the wave disturbs the
water.
• Wave speed increases with
wavelength.
6
7. Wave Height
Wave height is determined by:
the strength of the wind, the expanse of water that the wind blows across (or the fetch), & the length of time of the dust (or duration.)
Large storm waves have higher than average heights.
7
8. Breaking Waves
Ocean waves begin to lose energy
& slow down near the shore
because of friction with the ocean
bottom.
As the wave approaches more
shallow water, or water that is
half the wavelength or less deep,
the incoming wave crests gradually
catch up with the slower wave
crests ahead.
8
12. Tides
• Tides are the periodic rise &
fall of sea level.
• High tides are the highest
level to which water rises in
an area.
• Low tides are the lowest level
to which water recedes in an
area. 12
13. Tides
Generally, the daily cycle of tides is
determined by the Earth’s rotation &
the Moon’s orbit around Earth. As
the Earth rotates once on its axis (in
24 hours), the Moon is revolving
1/30th
of the way around in its orbit.
It takes a given location on Earth
about 50 minutes to “catch up with”
the orbiting Moon, so a particular
tide returns in approximately 24
hours & 50 minutes. 13
14. Differences in topography & latitude
cause three different daily tide
cycles.
The 3 tide cycles are:
1) Areas with semidiurnal cycles
experience two high tides per day.
2) Areas with mixed cycles have
one pronounced & one smaller high
tide each day.
14
Different Daily Tide Cycles
15. 3) Areas with diurnal cycles have
one high tide per day.
15
Different Daily Tide Cycles
17. Causes of Tides
• The basic causes of tides are the
gravitational attraction among the
Earth, Moon & Sun, as well as
the fact that gravitational
attraction decreases with
distance.
• The Moon has a greater affect
because it is closer to Earth. The
Sun, even though it is much larger
than the Moon, has a lesser affect
because it is farther from Earth. 17
20. Spring tides occur twice a month
during the full & new Moon. When
the Sun, Earth, & Moon are
aligned causing high tides to be
higher than normal & low tides to
be lower than normal.
20
Monthly Tide Cycles: Spring Tides
Spring think “straight line.”
21. Neap tides occur when the Sun,
Earth, & Moon form a right angle, as
seen during 1st
& 3rd
quarter Moon
phases. The gravitational pull of the
Sun & Moon “fight” each other, & we
notice smaller difference between
high & low tides. High tides are lower
& low tides are higher than normal.
21
Monthly Tide Cycles: Neap Tides
Neap think “ninety degrees.”
23. Ocean Currents
Currents are the movement of
water caused by differences in
temperature & salinity (density),
or caused by wind.
23
24. What causes the currents to flow in
different directions?
The CORIOLIS EFFECT
• The CORIOLIS EFFECT occurs
because Earth rotates East to West,
water and particles are deflected.
• In Northern hemisphere currents flow
clockwise & in the Southern
hemisphere currents flow
counterclockwise.
24
CORIOLIS EFFECT is responsible
for the patterns of currents &
WEATHER!
25. Surface Currents: Caused by the
movement of wind across the
oceans surface.
Deep or Denisty Currents: Caused
by the differences of temperature
or salinity of the water. 25
26. Surface Currents you need to know:
Gulf Stream, Canary, California,
North Equatorial, South Equatorial,
Kuroshio, East Australia, Peru,
Benguela, Antarctic Circumpolar,
Aguihas, North Atlantic, Greenland,
Labrador, & Brazil currents.
26
27. Deep Ocean or Denisty Currents:
Currents caused by the differences
in temperature & salinity. Not
affected by wind because they are
too deep.
These
currents are
known as
the Global
Conveyor
Belt.
27
28. Other Important Ocean Movements
Upwelling is where low-oxygen deep
water is moved up to the surface
due to differences in density. This
water is rich in nutrients which
supports marine life.
