Seawater

Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+
) and chloride (Cl−
) ions). Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about −2 °C (28 °F). The coldest seawater ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured −2.6 °C (27.3 °F). Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurements based on different reference scales may be up to 0.14 units.

Chapter 14

Chapter 14 is an American alternative metalcore rock band from Carlsbad, California consisting of vocalist Chad Ackerman (Destroy the Runner, As I Lay Dying, Austrian Death Machine), guitarist Tanner Sparks (Destroy the Runner), bassist Edwin Peraza, and Jonathan Knauer on drums.

Formation

Founded in 2003 by Ackerman and Sparks the band also consisted of drummer Mike Catalano (Chiodos, Destroy the Runner), guitarist Noah Slifka (In Fear and Faith) and bassist Eddie Hudson (Paper Mache). The band was unable to put together a full-length album but did complete two full U.S. tours and several demos without a label or financial backing.

Hiatus

After four years trying to land a record deal the band split up in 2007 when Ackerman and Sparks were offered the roles of vocalist and bassist for Destroy the Runner’s departing Kyle Setter and Jeremiah Crespo respectively. Noah Slifka went on to join In Fear and Faith the same year while Mike Catalano would join back up with Ackerman and Sparks in Destroy the Runner in 2008. Eddie Hudson moved on to play bass for the band Paper Mache.
