43. Ocean currents help regulate the climate and carry life-sustaining nutrients.
44. The ocean’s crust is a thin layer of volcanic rock called basalt.
45. The chemical ratio of salt to water in the oceans is fairly consistent across the world, a phe-nomenon known as “Forchhammer’s Principle,” af-ter the Danish scientist who discovered it.
46. Around 50 percent of the US lies beneath the ocean.
47. The oceans hold about 321 million cubic miles (1.34 billion cubic kilometers) of water, which is roughly 97 percent of Earth’s water supply.
48. The ocean’s canyons make the Grand Canyon seem small.
49. The oceans absorb the sun’s heat, transferring it to the atmosphere and distributing it around the world.
50. The ocean covers 71% of the Earth’s surface.
51. We have only explored about 5% of the world’s oceans. There’s a lot more to be discovered!
52. Life in the ocean depends on phytoplankton, mostly microscopic organisms that float at the sur-face and, through photosynthesis, produce about half of the world’s oxygen.
53. A single iceberg could supply a million people with drinking water for five years
54. Ninety percent of the earth’s volcanic activity happens in the ocean.
55. The ocean’s sea level rise, caused by melting glaciers and ice sheets and the expansion of sea-water as it warms, poses a significant threat to coastal communities and infrastructure.
56. The Pacific Ocean is the world’s largest ocean and contains around 25,000 islands.
57. It also holds about 96.5% of all Earth’s water – that’s a volume of 320 million cubic miles!
58. The Southern Ocean is geologically the youngest ocean.
59. The Southern Ocean was not declared an ocean until very recently.
60. The Atlantic Ocean is the second-largest ocean and the youngest of the five major oceans.
61. The ocean’s carbon cycle, the exchange of carbon dioxide between the ocean and atmos-phere, plays an important role in regulating the Earth’s climate.
62. The Great Barrier Reef covers an area of 350,000 square kilometers.
63. One percent of the ocean is covered in coral reefs.
64. The deepest point of the ocean is almost 40,000 feet!
65. The ocean’s currents can carry pollutants and debris around the world, causing environmental and health problems.
66. The Atlantic Ocean is the first ocean to be crossed by both a ship and an aircraft.
67. The ocean’s rip currents are the biggest dan-ger you face at the beach.
68. Pressure at the bottom of the ocean would crush you like an ant.
69. Water at the bottom of the ocean is incredibly hot.
70. The Pacific Ocean is wider than the moon.
71. There are more historic artifacts under the sea than in all of the world’s museums.
72. Less than 10% of the world’s ocean, and less than 50% of U.S. waters, have been mapped.
73. Rubber ducks have helped shape our under-standing of the ocean currents.
74. Sea level and the amount of water in the ocean change over time.
75. Ferdinand Magellan named the Pacific Ocean.
76. The Great Lakes aren’t oceans, but they’re similar in many ways.
77. 37 out of 50 critical minerals can be found in the ocean!
78. Sounds can travel to the deepest explored ar-eas of the ocean.
79. The number of species that live in the ocean is unknown.
80. The Dead Sea is almost nine times as salty as the ocean.
81. It’s possible to find rivers and lakes beneath the ocean.
82. The Pacific Ocean was once considered peaceful.
83. Ocean currents can be warm or cold.
84. Plankton are the foundation of the marine food chain
