Abstract:
Approximately 130+ observations of marine mammals species were recorded, along with the date, time, approximate weather condition, sea condition, and approximate distance and azimuth from an observation point onshore (point of regular observation: 12° 57' 53"S - 40° 31' 51" E). To increase accuracy of observation locations, I went to sea and took waypoints of where I observed the dolphins and whales. I then mapped these points on the nautical map of the region (new 2010 version - WGS 84). The original estimated distances were overestimated by far and the azimuth I was measuring was not that precise. Therefore, when I transformed the distance and azimuth of my observations I took these parameters into consideration and corrected them. The azimuths measured are accurate at 2 degrees. I estimate that the coordinates have a precision of about 0.1 to 0.2 minutes.

In addition, direct observations while swimming 11 times (for one hour each time) next to them allowed closer observations. Observations were also made to identify 163 species of fish (on coral reef mainly) and geographic coordinates were recorded while regular diving and snorkeling within that zone.

Purpose:
Opportunistic observations were conducted on shore mainly from a terrace (about 10 to 12 m above sea level). All observations have been within a radius of less than 3 nautical miles from the point of observation on shore (binoculars 10x - 30x). For the observations that have not been from that reference observation spot, I recomputed the azimuth from the reference.

There were three species observed, mainly <i>Tursiops aduncus</i>, which seems to be a resident in the area. What I observed was that the animals were cruising always in the same area, day after day. Day after day, I could also recognize that it is the same group as one of the individuals has a dorsal fin cut! Group numbers are rough estimates.

Supplemental information:
Group estimates were provided as a range or a minimum estimated number of animals; observed counts used were the median of the range (rounded down) or minimum number (when the minimum number of animals was recorded instead of a range) to be conservative.

Abstract:
In altricial mammals, the mother’s care and attendance are essential for the young to acquire survival skills. Not much is known about mother-pup behavior in the sea otter population of Simpson Bay, Prince William Sound, Alaska, United States. In these studies, firstly, water depth and location of feeding females with pups of different ages were recorded (global positioning system [GPS] locations of the sea otters are given in the map). Secondly, boat locations were noted when females with pups were observed for 24 hour activity budgets (GPS locations of the boat are given in the map). Weather, time and tidal conditions were also recorded and tested on the influence on sea otters behavior.

Abstract:
This 1993 line-transect survey was designed to make abundance estimates of the northern stock of common dolphin, <i>Delphinus delphis</i>, in the eastern Pacific. This stock of dolphin is taken in the tropical tuna fishery. The index of relative abundance for this stock, computed from sightings on tuna vessels, has declined substantially in the last decade. However, because tuna vessels cover only the southern portion of the stock's range, the declines in the index may be due to a northward shift in distribution, rather than an 
actual decline in abundance. The 1993 survey was designed to produce the first range-wide estimates of abundance for the northern common dolphin and its recently described congener, <i>Delphinus capensis</i>. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA Ships <i>McArthur</i> and <i>David Starr Jordan</i> for a combined total of approximately 32,000 kilometers surveyed from late July to early November 1993. This dataset provides the time-date and geographical coordinates, by 
species/stock, of all cetaceans detected during the survey, as well as the daily and intra-daily start and end points of the line-transect survey by the NOAA Ship <i>McArthur</i>.

Purpose:
The primary objective of the cruise was to survey the area inhabited by the northern stock of common dolphins, and to make an estimate of its absolute abundance in order to assess the impact of the dolphins killed by the United States and international yellowfin tuna purse seine fleet in the eastern tropical Pacific.

Abstract:
The continental shelf of Southern Brazil is an important feeding ground for loggerhead sea turtles and for fishing activities. This overlap leads to a high bycatch and mortality of this endangered sea turtle. The aim of this study, with the use of satellite telemetry, are to: i) determine the spatial and temporal patterns of sea turtles distribution in the area; ii) identify preferred areas of use by immature individuals on the continental shelf; and iii) determine the influence of environmental variables such as sea surface temperature and depth on the species distribution.

Abstract:
Turtles are an important component of the ecosystem, and may serve as a key biological indicator of the health of their environments. They are constantly impacted by a variety of both natural and anthropogenic factors.Satellite telemetry is a powerful tool for examining short- and long-term movements of these protected species and enhancing conservation and management efforts. These observations will allow us to examine how much time these turtles actually spend in the Mississippi Sound and what microhabitats they utilize. The use of satellite tags on recently rehabilitated and released sea turtles will increase our knowledge about the daily activities and habitat fidelity of these animals.

Abstract:
From 4 to 13 August 1991, as part of a larger study, Alaska harbor porpoise (<i>Phocoena phocoena</i>) abundance was investigated during an aerial survey throughout the coastal waters of Bristol Bay. A Twin Otter was used as the survey platform. The surveys were flown at an altitude of 152.2 m (500 ft) and at an airspeed of 185 km/h. A single zigzag trackline was flown along the north side of Bristol Bay, and the first of three identical sawtooth tracklines was flown along the south side. Line-transect methodology was used, and only those observations made during optimal conditions were analyzed. Density of harbor porpoises was calculated using line transect estimates based on perpendicular distances of sightings to the cruise track of the airplane. On average, porpoise group size and density for Bristol Bay was 1.17 (SE = 0.35) and 4.48 groups/100 km2 (SE = 1.38).

Purpose:
Although harbor porpoises, <i>Phocoena phocoena</i>, are known to occur throughout Alaska waters, few estimates of abundance exist. In 1991, the National Marine Mammal Laboratory initiated a 3 year study on Alaska harbor porpoises. The objectives of this program were to: 
1) Obtain minimum population estimates in coastal waters using line transect methodology with a coefficient of variation for density estimates of less than 30% for each survey area, and 
2) Establish a baseline for detecting changes in abundance through time, for analysis of trends.
During the present study, it was not fiscally possible to survey all areas of the state in any one year. Accordingly, we selected sections of the state to survey in consecutive years to maximize the likelihood of including all of the animals for a particular area surveyed while minimizing the likelihood of significant movement between areas among survey years.

USGS South Florida Fish and Invertebrate Assessment Network Harvest

Keywords: Observation, Occurrence
Temporal coverage: 2005/2007

The South Florida Fish and Invertebrate Assessment Network (FIAN) is a monitoring project within the Comprehensive Everglades Restoration Plan (CERP). It is an element of the Southern Estuaries module of the Monitoring and Assessment Plan (MAP).

The FIAN is designed to support the four broad objectives of MAP: (1) to establish a pre-CERP reference state, including variability, for each of the performance measures; (2) to determine the status and trends in the performance measures; (3) to detect unexpected responses of the ecosystem to changes in stressors resulting from CERP activities; and (4) to support scientific investigations designed to increase ecosystem understanding, cause-and-effect, and interpretation of unanticipated results.

FIAN is a regional scale monitoring program of seagrass-associated fish and invertebrate (penaeid and caridean shrimp and crabs) communities present in shallow waters of South Florida; the pink shrimp, Farfantepenaeus duorarum, as a restoration indicator, is a species of special interest.  FIAN provides input to the pink shrimp performance measure. The pink shrimp emerged as an ecosystem attribute to be monitored from the Florida and Biscayne Bay conceptual ecological models.

A 1-m2 throw-trap is the basic gear used to sample fauna in FIAN.  Associated with each throw-trap animal sample are measurements of seagrass/algae habitat, water depth, sediment depth and surface temperature, salinity and turbidity.  Twice annually, a randomly located throw-trap sample is collected in each cell of a 30-cell grid at each of the 19 monitoring locations at the end of the dry season (April/May) and the wet season (September/October).

This dataset describes the quantification of the seagrass using a harvest method (Robblee et al 1991)

Abstract:
The ship survey was performed from 29 July 1992 to 06 September 1992,
starting and ending in Woods Hole, MA. The study area, covering approximately 13,300 nmi2, was from Portland, ME to St. John, New Brunswick over to Port Joli, Nova Scotia on the southeast side of Nova Scotia.

Purpose:
PRIMARY OBJECTIVE
Estimate the abundance of harbor porpoises in the Gulf of Maine - Bay of Fundy - Scotian shelf
area.

SECONDARY OBJECTIVES
1) Determine the spatial distribution patterns of harbor porpoises, and investigate if the patterns are correlated with hydrographic or biological features, such as, the depth, temperature or salinity of the water or with targets seen on an acoustic fish finder.
2) Estimate the abundance and spatial distribution of other cetaceans.
3) Determine if harbor porpoise avoid this ship, and if so, at what distance.
4) Use a 17 foot Zodiac rigid-hulled inflatable boat (RIB) and the R/V Abel-J to survey the Penobscot Bay - Blue Hill Bay area and other bays and harbors along the Maine and Nova Scotia coast.
5) Determine if there is a spatial distribution pattern of mother-calf pairs of harbor porpoise.
6) Compare the abundance estimate and spatial distribution of harbor porpoise as seen this year with that seen in previous years.
7) Determine dive time patterns of individual and groups of harbor porpoises around the sighting platform.
8) Investigate the utility of 2 new electronic data entry systems.
9) Determine the distribution of marine mammals between the northeastern edge of the study area and Halifax, Nova Scotia, on Brown' s Bank, and on the continental shelfbreak in the area south of Brown' s Bank.

Supplemental information:
In addition to the sighting data, effort data was recorded  every half hour or whenever conditions change.
This dataset, therefore, should be used with the effort data.
