Land & Sea Surveying Concepts is a full-service land and hydrographic surveying firm providing multi-disciplined surveying services since 1992. Our expert staff has is experienced in providing conventional, hydrographic, and GPS (static and RTK) surveying. 

We are located on the central East coast of Florida, but have surveyed as far away as Ascension Island in the South Atlantic. Our crews and equipment can be mobilized to your site, no matter where it is. Our team prides itself on our attention to detail and customer service while providing accurate and efficient products.
COMPANY HISTORY AND EXPERIENCE
Since our inception, we have completed thousands of surveys and worked for numerous private industry clients as well as many governmental entities including the Sebastian Inlet District, the Jupiter Inlet District, the US Army Corps of Engineers, the St. Augustine Port, Waterway & Beach District, the Canaveral Port Authority, the City of Ft. Pierce, the City of Miami, and the City of Gulfport. The principal, Tim Carlile, holds Professional Surveyor licenses in five states (Florida, Geogia, Mississippi, Louisiana, and Texas) and is a registered Land Surveyor in the US Virgin Islands. He holds a USCG 50-ton Captain's license with his ACSM Hydrographer certification pending.

Our experience covers, but is not limited to, upland and submerged land lease boundaries, topographic surveys, hydrographic, bathymetric, and as-built surveys. We are also experienced on remote operated vessels (ROV), Ultra Short Base Line (USBL) diver positioning and tracking systems, Conductivity, Temperature, Depth (CTD) sensors, Acoustic Doppler Current Profiler (ADCP), wave meters and tide gauges. Land & Sea Surveying prides itself on its commitment to maintaning a complete knowledge of the practice of surveying and the new technology as it emerges and implementing this knowledge to provide the highest level of service to our clients. 

Land & Sea Surveying now uses a wireless and baseless RTK GPS surveying system for all GPS surveying applications, upland and onboard our hydrographic surveying vessels. The system uses reference stations all over the state of Florida as well as the Southeast United States. Having the RTK GPS tied to the hydrographic survey system provides vertical positioning as well as horizontal, to subcentimeter accuracies. This eliminates the need to rely on tide stations while providing a greater level of accuracy in areas of extreme tidal variations.

Additional Project Experience
Sebastian Inlet, Tide Pool and Dredged Material Management Area - May 2011
In May 2011, we completed a project with the Sebastian Inlet District that consisted of maintenance dredging of the tide pool area and constructing a Dredged Material Management Area (DMMA). We have worked with the District from the beginning of this project establishing a lease parcel boundary of the proposed area and conducting a topographic survey with wetland and tree location for design of the DMMA. We provided construction staking for the installation of silt fencing, of the contours for dredging, for the construction of the DMMA berm and drainage structures, and location of the transformer pad. Final as-built surveys were completed for the tide pool area and the DMMA with all submittals being accepted by the permitting agencies.
Jupiter Inlet, Channel and Inlet Dredge Survey and South Beachside Fill - March 2011
Land & Sea completed this project in Jupiter for the Jupiter Inlet District. The project consisted of dredging the inlet channel and sand trap area and placing fill on the beach south of the inlet. This was a two phase project with Phase I completed in early 2010 and Phase II completed in March 2011. Land & Sea Surveying provided stake-out for the beach fill area as well as hydrographic surveys of the dredge areas. Surveys were completed for pre-construction conditions, interim and post-construction conditions with cross-sections and material quantities.
Gulf of Mexico - HYPACK Navigation and Environmental Sampling - Sept. 2010 -Nov. 2011
For 18 months, Land & Sea Surveying worked on a project in the Gulf of Mexico which involved using HYPACK to navigate 165 to 210 foot vessels. The project also involved collecting environmental samples, operating an ROV with HD video and soil sampling equipment, acquiring water column data with CTD Sensors, and mapping with single and multi-beam hydrographic systems.
St. Lucie Inlet, Martin County - USACE Project ICWW/OWW Maintenance Dredging
From November 2009 to March 2010, Land & Sea Surveying worked on the USACE project ICWW/OWW Maintenance Dredging, Cross-Roads, Martin County. We provided staking of the proposed dredge area as well as hydrographic surveys for pre-constuction conditions, interim surveys for completed sections, and as-built surveys with quantity calculations at each stage. Surveys were also performed of the spoil area.

February 2012: Hydrographic surveying projects in Tampa Bay area using Reson SeaBat 7125 Multibeam System with Side Scan and the new SeaArk Survey Vessel "The Beast"
Land & Sea Surveying was contracted to survey an area surrounding a pipeline exposure to search for any objects that may pose a hazard to anchoring of a barge for repairingthe exposure. We surveyed the area using the SeaBat 7125 for bathymetric and side scan data and the Geometrics G-882 Marine Magnetometer.
Land & Sea Surveying also performed a survey of a second pipeline in the Tampa Bay area to determine the depth of cover. In performing this survey we located the pipeline using the Geometrics G-882 Marine Magnetometer, then surveyed the area using the SeaBat 7125 multibeam to search for pipeline exposures and a SDI singlebeam 200kHz systems for bathymetry. To determine depth of cover, we utilized the SDI BSS+5 sub-bottom profiler system with 12, 50, and 200 kHz transducers.
March to May, 2012: Land & Sea Surveying collected images of wrecks off the coast at Cape Canaveral, Florida using Reson Seabat 7125 Multibeam System with PDS2000 software
"Dutch Wreck" -- Steamship Laertes

The Dutch steamship Laertes was built in 1919 by Taikoo Dockyard & Engineering Company, Hong Kong. Owned by Nederland Stoomy, she was 423.9 feet long, had a 52.3 foot beam, displaced 5,825 tons and was pushed by a single screw triple expansion engine. The Laertes was powered by a 413 nhp triple expansion engine and had a top speed of 13.5 knots.


On May 3, 1942, the Laertes was torpedoed and sunk by a German submarine. Some say it was the work of the U-564, while others claim it was the U-109. At the time she was on a voyage from New York to Bombay, with a 5,230 ton cargo of war supplies, including three aircraft, 17 tanks and 20 trucks. A total of 18 of her crew went down with her.

Today the Laerte's scattered wreckage sits in 72 feet of water eleven miles off Port Canaveral. This wreck is also locally known as the Dutch Wreck.
SS Leslie

The SS Leslie was built in 1919 in Duluth, Michigan, as the Lake Flagstaff. She later sailed under the names Stella Lykes and Josephine, before being renamed Leslie. She was 251 feet long, had a 44 foot beam and displaced 2,609 gross tons. The Leslie was owned by Worth Steamship Company of New York and was under the command of Captain Albert Ericksson. On April 12, 1942, she was torpedoed by the German submarine U-123. At the time she was en route from Antilla, Cuba, to New York with a cargo of 3,300 tons of sugar. Out of a complement of 31 crew and one passenger, four of her crew were lost.

Today the Leslie wreck sits in 80 feet of water, 21 miles off Port Canaveral.
"Sub Wreck"

This artificial reef, while locally known as the "Sub Wreck", is actually old camera observation tower debris from the space center.
July 23, 2012: Submerged Cable Location in Elizabeth River, Portsmouth, Virginia for Level 3 Communications
Land & Sea Surveying located a submerged Level 3 fiber optic cable in the Elizabeth River with depth of burial. The horizontal position of the cable was marked and depth of burial was provided to avoid damage to the cable from construction.
July - August 2012: Summer 2012 Survey at Sebastian Inlet
Land & Sea Surveying performs a survey of the inlet with beach profiles to the north and south every six months. This summer the survey also included a post-dredge survey of the channel from the inlet to the Intracoastal Waterway.
The pictures below show images of the reef above surveyed with the Reson 7125 Multibeam Survey system. We collected the data using Reson's PDS2000 software. The data shown is approximately 17,000 feet long and 3,500 feet wide. The data was collected on a 2-foot cell grid and we were able to complete the survey with 1.5 days in the field and about 4 hours post-processing. From the data, we are able to produce geo-referenced TIFF or JPEG files (as shown below) and an ASCII file with accuracies to plus or minus 0.10 feet. We collected simultaneous 200kHz single beam data which was compared to the 400 kHz multibeam data with fantastic closures.

March 2013: Land & Sea Surveying surveys the Ocean Venus (AKA the "Lead Wreck") off coast of Cape Canaveral, Florida.
The Ocean Venus "Lead Wreck", a British freighter, was sunk by a German U-boat on May 3rd 1942. It was later flattened for navigation purposes. The ship was known for its cargo of lead, though it held 9,450 tons of general cargo including 4,000 tons of lead, 4,000 tons of lumber, 80 tons of acetone and 1,000 tons of canned herrings. The ship was torpedoed and sunk by U-564 commanded by Reinhard Suhren. The Master, Captain John Park, 37 crew and 4 gunners landed at Cape Canaveral. Five crew were lost. Now mainly stripped of its cargo, the ship sits in approximately 80 feet of water out of Port Canaveral and is host to many different species of fish and marine life.


Ocean (British Liberty) Class Merchant
Steamship
The ship was built by Permanente Metals Corp in Richmond, California for the British Ministry of War Transport and was one of sixty Ocean (British LIberty) class merchant ships. The ship's measurements were registered at 441.5 x 57 feet. Gross tonnage was 7,174 and deadweight was 10,500 tons. Speed was 11 knots.
