Hassler (vessel)
The schooner ''Hassler'' was the first iron- hulled steamship used in the service of the United States Coast Survey. Ship history Plans for a new ship to chart the waters of U.S. Pacific Coast were drawn up in early 1870 by Carlile Patterson, the hydrographic inspector of the U.S. Coast Survey. Patterson called for an iron-hulled ship of about 325 gross tons, with a draft of no more than and a top speed of . He required that the ship use no more than 2½ tons of coal per day and could hold up to two months of provisions for a crew of 37.

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 35,800 species of fish had been described as of March 2025, with approximately 250 new species described each year. Etymology The word is derived from the Ancient Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λόγος, ''logos'', meaning "study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were hunters and gatherers who had learned how to obtain the most use ...
